At North County Aesthetics & Implants, finding a dental practice that treats every visit as more than a routine checkup starts with Dr. Khizer Hafeez, D.D.S., the practice’s current owner, and the team he leads today. Patients across San Marcos, Rancho Bernardo, and Escondido come in dealing with some of the most consequential dental problems they face: tooth loss, cosmetic concerns, and structural damage that affects how they eat, speak, and feel about their smile. A single missing tooth, worn enamel, or a failed crown can lead to the same place: care available here, under one roof, at a practice with roots going back more than three decades to Dr. Nelson Y. Howard.
Our Mission
Too many patients get a recommendation before anyone explains what’s actually wrong. That’s not how appointments go under Dr. Khizer Hafeez, who owns the practice today and spent years researching cardiovascular disease before he ever treated a patient, training that pushes him to look at the complete picture rather than react to the symptom in front of him.
Dr. Nelson Y. Howard held the practice to that bar from day one, back in 1992, and it hasn’t loosened since ownership changed hands. A cleaning, a filling, and a full implant case all move through the same sequence: examine first, explain second, treat third. If a recommendation doesn’t make sense to you, that’s a sign something needs to be explained better, not a sign you should just go along with it.

Why Choose Us
Every dental office can list its equipment on a website. What actually matters is what a visit feels like once you’re the one being treated. These are the five things that tend to stand out to people who’ve experienced it firsthand.
A Standard Set in 1992, Still Held Today
A founding story matters less than whether a practice kept its standards after leadership changed hands. Here, it did: three decades of clinical history back this team, not just one doctor’s tenure. (More on that under Meet the Team below.)
A Digital Workflow That Skips the Outside Lab
A digital scan with the Trios 6 is all it takes to start designing a crown or veneer, and in-office SprintRay equipment carries that design through to a finished piece without an outside lab ever entering the picture. There’s nothing to wear between visits and no trip back later to swap it for the real thing. For patients balancing work and family schedules, that’s fewer trips to the office, not more.
Two Offices, One Standard of Care
Getting to San Marcos may be easier for some patients, and Rancho Bernardo easier for others, but neither location means a scaled-down version of care. Both locations pull from the same digital scanning and in-office production equipment, and the same clinical team oversees treatment across both. Picking a location comes down to which drive is shorter, not which office has the better setup.
A Complex Case Stays With People Who Already Know You
Say a cracked molar ends up needing a root canal, then a crown, then a follow-up look at your bite once it’s restored. That’s three different steps, but it doesn’t mean three different offices or three sets of new-patient paperwork here. Dr. Hafeez and Dr. Ayazi coordinate each phase directly, so nothing gets lost in a handoff between providers who’ve never seen your chart.
Results You Can See Before You Commit
Patient outcomes are documented in an open smile gallery, and patient feedback is shared through testimonials rather than kept off the site. That kind of openness reflects a practice willing to be judged by its actual work, not just its marketing copy. You can look at real results before deciding whether this is the right fit for your smile.
Meet the Team
Dr. Nelson Y. Howard founded this practice in 1992; his four-decade career earned him accreditation with the American Academy of Cosmetic Dentistry and helped establish the West Coast Society for Cosmetic Dentistry. Dr. Khizer Hafeez now owns the practice; a graduate of New York University College of Dentistry, his prior research into cardiovascular disease still informs how he diagnoses and plans treatment today. Dr. Dariyan Ayazi is also part of the clinical team. Full bios, training details, and credentials for all three doctors are available on the Meet the Dentists page.

Dental Implants
Is dental implant treatment right for you?
A gap where a tooth used to be doesn’t just affect how your smile looks in photos. It changes how you chew, how neighboring teeth shift over time, and how much bone your jaw retains in the months that follow. If you’re weighing implant treatment, the questions below can help you think through your situation before your consultation.
Who is a candidate for dental implants?
Patients missing one tooth, several teeth, or a full arch may qualify for implant treatment. The main factors are general health, available bone at the implant site, and whether any systemic conditions are well managed. Patients with uncontrolled diabetes, active gum disease, or significant bone loss may need preparatory treatment before implants can be placed. Single implant crowns, implant bridges, implant-supported dentures, and All-on-X suit different patterns of tooth loss.
What does the dental implant process involve?
A 3D scan with the Trios 6 digital scanner maps your teeth, gums, and jaw before any implant work begins, replacing the need for a physical impression tray. Depending on your case, treatment may involve a single implant crown, a 3 on 6 restoration, All-on-X, or immediate implant placement. Immediate placement means the implant goes in at the same appointment as the extraction, which can reduce total treatment time. The plan that follows is based on what the scan actually shows, not a one-size-fits-all protocol.
When Is the right time to consider dental implants?
Acting sooner rather than later matters more than most patients expect. Once a tooth is gone, the jaw bone beneath it begins to shrink within the first year. The longer it goes unaddressed, the more likely bone grafting will be needed before an implant can be placed. For some patients, immediate placement at the time of extraction can preserve bone and shorten the overall process. Properly maintained implants are designed to last for decades.
Why dental implants over the alternatives?
Consider what actually holds each option in place. A bridge borrows its strength from the two teeth next to the gap, which get filed down so the false tooth has something to grip. A denture skips that cost, but it never reaches the bone, so nothing tells it to stick around. An implant goes where the root used to be, giving the bone something to hold onto again.
A 2022 systematic review and meta-analysis in Clinical and Experimental Dental Research compared implant-supported removable dentures against conventional dentures across thirteen studies and found that implant-supported removable dentures improved patients’ overall quality of life and satisfaction, a difference the reviewers found to be statistically significant.
Delaying Implant Treatment Shrinks the Window for a Straightforward Solution
When a missing tooth goes unaddressed, the problem isn’t limited to the space itself. The tooth in the opposing arch, no longer meeting resistance when you bite, gradually shifts further than it should, a process clinicians call supra-eruption. That shift narrows the space available for a future restoration and can pull the opposing tooth’s root surface into view, occasionally turning a simple case into a full mouth reconstruction.
Research published in the Journal of Clinical and Diagnostic Research and indexed on PubMed notes that this altered alignment may expose the root surface, increasing the risk of gingival recession, added sensitivity, and a higher chance of decay. Replacing a missing tooth sooner avoids that second problem stacking on top of the first.
Cosmetic Dentistry
Is cosmetic dentistry right for you?
A smile that chips, stains, or simply doesn’t reflect how you feel is something many patients live with longer than they need to. Prepless veneers, smile makeovers, and teeth whitening aren’t one-size-fits-all decisions. The right path depends on what’s happening beneath the surface. The questions below can help you decide whether a cosmetic treatment makes sense for your situation right now.
Who is a candidate for cosmetic dentistry?
Patients bothered by discoloration, chips, uneven spacing, or proportion concerns are common candidates for cosmetic care. Prepless veneers are a good fit when teeth are already structurally sound, and the issue is purely how they look. Patients with active decay or gum disease need to address those issues before cosmetic work begins. Patients with significant bite problems may need to address those first as well. A smile consultation is the right starting point for figuring out which treatments fit your specific situation.
What does the cosmetic dentistry process involve?
Cosmetic treatment planning starts with a thorough look at what’s already in your mouth. The Trios 6 scanner captures detailed images of your teeth and gum tissue. For veneers, SprintRay technology 3D-prints restorations in-office, which means faster turnaround than traditional lab fabrication. ClearCorrect clear aligners may be part of a broader smile makeover when alignment needs to be corrected first. Teeth whitening is often the finishing step after veneer or aligner treatment is complete.
When is the right time to consider cosmetic dentistry?
Cosmetic treatment gives the most consistent results when your gum health is stable and any prior restorative work is done. Patients who’ve recently finished orthodontic treatment are often ready for veneers or whitening once their bite has settled. If you’re considering both ClearCorrect and veneers, alignment comes first. Redoing veneer work after teeth shift is avoidable with the right sequence. Properly placed and maintained veneers can last many years, though their longevity depends on the health of the tooth underneath.
Why cosmetic dentistry over the alternatives?
Leaving cosmetic concerns alone doesn’t keep them static. Chips grow, staining deepens, and gaps widen, and spot treatments like whitening alone rarely hold when the real issue is shape or proportion. A coordinated smile makeover addresses several concerns in one visit, with more consistent results than tackling them one at a time.
There’s also a bonding advantage: a peer-reviewed case series published in the journal Medical Science found that prepless veneers involve no removal of tooth enamel during teeth preparation in most cases, unlike traditional veneers, which typically require reducing 0.5-0.7 mm of enamel. Bonding to untouched enamel tends to hold up more reliably than bonding to a surface that’s been reduced and roughened.
Cosmetic Concerns Can Signal Structural Problems That Worsen Without Evaluation
Chips and worn edges aren’t always surface issues. They can indicate bite dysfunction, enamel erosion, or early TMJ involvement that can worsen without attention, and discoloration in a single tooth may point to internal damage or a failing root. Patients who put off cosmetic evaluation sometimes find a surface issue has become a structural one requiring more involved treatment.
A review of enamel erosion mechanisms published in the British Dental Journal and indexed on PubMed notes that acid-mediated softening of enamel will progress to irreversible loss of surface tissue if left unchecked, potentially exposing the underlying dentine. Early evaluation keeps options open and costs lower.
Restorative Dentistry
Is restorative dentistry the right next step for you?
Structural dental damage rarely stays contained to a single tooth. A cracked tooth, a failing filling, or an untreated infection can affect nearby teeth and the bone beneath them if left alone. If you’re dealing with pain, sensitivity, visible damage, or a broken-down restoration, the questions below can help you understand where restorative care fits into what you need next.
Who is a candidate for restorative dentistry?
Patients with decay, fractures, infection, or worn-out prior restorations are candidates for restorative treatment. Crowns are appropriate when a tooth has lost enough structure that a filling can’t reliably hold it together. Root canals are needed when infection reaches the tooth’s inner tissue. Extractions and bridges apply when a tooth can’t be saved or has already been lost. Many patients come to restorative care after years of patchwork treatment that’s finally reached its limit.
What does the restorative dentistry process involve?
We take digital impressions with the Trios 6 scanner before fabricating any crown or restoration. We produce same-day crowns in our office using SprintRay Pro 2S, SprintRay Midas, and SprintRay NanoCure technology. We design, print, and deliver the crown in a single visit. There’s no temporary crown to manage between appointments. We check fit and function before you leave. For root canals, we remove infected tissue and seal the tooth before placing a crown to protect what remains.
When is the right time to consider restorative dentistry?
Pain, sensitivity to heat or cold, visible cracking, or a chipped or shifted restoration are all signals that restorative treatment shouldn’t wait. Same-day crowns made with SprintRay technology function and last as long as crowns made in an outside lab, without the two-to-three-week wait between appointments. When extraction is necessary, timing matters. The surrounding bone begins to change once a tooth is removed, which affects what replacement options are available and how straightforward placement will be.
Why same-day restorations over traditional multi-visit approaches?
Traditional crown work means two appointments, weeks apart, with a temporary crown in between that can fail, come loose, or break before the permanent one arrives, plus a second injection of anesthetic at the follow-up visit. Our in-office process uses digital scanning and SprintRay fabrication to complete the crown in one appointment, with no temporary and no second visit.
A randomized clinical trial published in Clinical Oral Implants Research and indexed on PubMed compared digital scanning against conventional impression-taking for posterior crown restorations and found that the digital workflow resulted in shorter adjustment times at try-in than conventional impressions, with a proper fit achieved on the first try far more often.
Untreated Decay Moves Faster Than Most Patients Expect
Decay doesn’t stay contained. Once it reaches the inner layers of a tooth, infection can move to the root and then the surrounding bone, turning what could have been a filling into a root canal, then a crown, then potentially an extraction, with each step adding cost and time. In serious cases, untreated dental infection can spread beyond the jaw entirely.
A case report published in Case Reports in Emergency Medicine and indexed on PubMed describes a child who developed a brain abscess from an untreated dental infection and concludes that treating dental infections may prevent a potentially life-threatening condition that physicians rarely consider. Treating damage early is consistently simpler than treating what happens when it’s left alone.

FAQs
Do you accept appointments?
Yes, we do accept appointments at our dentist’s office. In fact, we highly recommend that you schedule an appointment with us in advance to ensure that you receive the best possible care.
Do I need to arrive early for my first appointment?
Yes, please arrive at least 10-15 minutes early to fill out any patient forms.
How many dental appointments do I need each year?
Every one of your family members should be visiting the dentist at least twice a year. Biannual checkups and cleanings are crucial for preventing tooth decay, cavities, gum disease, and other dental problems. We’ll let you know if you need more frequent appointments depending on the state of your oral health.
What forms of payment do you accept?
We accept checks, cash and credit cards. Please bring your insurance information to your appointment or submit it online in advance to find out if we accept your plan at our office.
What happens during a same-day crown or veneer appointment?
A digital scan with the Trios 6 replaces the old-fashioned impression tray, and that scan goes straight into designing your crown or veneer without a physical mold. SprintRay Pro 2S, SprintRay Midas, and SprintRay NanoCure equipment then produce the finished piece right in the office. Most patients leave the same day with a permanent restoration already in place, without a temporary to manage in between visits.
What if jaw pain is the real problem, not a tooth?
A specific tooth doesn’t always cause jaw pain, clicking, or morning headaches. TMJ & TMD treatment addresses problems with the jaw joint itself, which can sometimes be mistaken for a dental issue. A short evaluation usually clarifies whether the discomfort comes from a tooth, the bite, or the joint so the right plan can be built around the actual cause.
Can gum health affect the rest of a smile?
Yes. Gum disease left untreated can affect the bone that holds teeth in place, which is why periodontal therapy & dental cleanings are treated as a foundation for other treatment, not an afterthought. Cosmetic work like veneers or teeth whitening tends to hold up better once gum health is stable. Routine cleanings are the simplest way to catch early warning signs before they turn into bigger problems.
Does the practice's founder still see patients?
Dr. Nelson Howard founded the practice in 1992 and built its reputation over more than four decades, but he’s the former owner and no longer treats patients day-to-day. Dr. Khizer Hafeez now owns and leads the practice, continuing the same standards Dr. Howard originally established. That transition kept the clinical history intact while bringing in current, hands-on ownership for today’s patients.
What services are available under one roof?
This practice combines dental implants, cosmetic dentistry, and restorative dentistry under one roof, along with emergency dentistry, TMJ & TMD treatment, and periodontal therapy & dental cleanings. Specific options range from All-on-X and implant-supported dentures to veneers, teeth whitening, ClearCorrect clear aligners, dental bridges, and root canals. A smile consultation is the simplest way to determine which option fits your situation.
How can I improve my smile?
That depends on what’s bothering you about your smile’s appearance in the first place. Our cosmetic dentists in San Marcos and Rancho Bernardo have many ways to transform your teeth, from veneers that can correct several imperfections at once to professional whitening that can remove stains on and beneath your tooth enamel. We can plan your smile makeover during an initial consultation where you tell us all about the improvements you have in mind.
Do I need to fill a gap from a missing tooth in my smile if no one else can see it?
Yes! You need your teeth for more than smiling. They also play an important role in chewing and speaking, and they prevent your jawbone from eroding over time due to a lack of blood flow. Your oral health will suffer no matter which tooth is missing, which is why it’s important to find a replacement as soon as you can. We generally recommend dental implants for the best-looking and longest-lasting results.
What can I do if my teeth are spaced unevenly?
Closing a small amount of space in your smile could be a lot simpler than you might think. In some cases, it can be done in just one visit with the strategic application of composite resin. Veneers can also be used to hide such gaps, although they usually take at least two visits to place.
What does a dental emergency look like?
A dental emergency is usually characterized by severe or persistent oral pain and/or visible damage to your teeth. Let us know right away if you’re suffering from a broken or knocked out tooth, a toothache that does not get any better, visible swelling in your mouth, or a loss of a dental restoration. These issues all need to be dealt with immediately if you don’t want them to grow worse.
