Care That Goes Beyond the Ordinary

Not every dental concern can be resolved with a routine visit. Some conditions — chronic jaw pain, recurring cold sores, bite dysfunction, or sudden dental trauma — require a higher level of clinical expertise, advanced technology, and a treatment philosophy built around the whole patient, not just the symptom.


At Lazare Biomimetic Dentistry & Smile Design on Manhattan's Upper East Side, Dr. Marc Lazare offers a focused suite of specialized treatments for patients whose needs extend beyond conventional dental care. Each protocol is minimally invasive, evidence-informed, and personalized for lasting relief. Our specialized services include TMJ Infrared Light Therapy, TMJ Nightguards, EMFACE® Therapy, Cold Sore Laser Treatment, and Dental Emergency care.

TMJ Disorders: More Than Just Jaw Pain

The temporomandibular joint (TMJ) connects the lower jaw to the skull and plays a central role in every bite, word, and expression. When this joint — or the muscles surrounding it — becomes stressed, inflamed, or misaligned, the effects can extend far beyond the jaw itself.


TMJ disorders are among the most underdiagnosed conditions in dentistry. Patients often experience a combination of symptoms: persistent jaw pain or soreness, clicking or popping sounds when opening the mouth, teeth grinding or clenching (bruxism), morning headaches, earaches, facial fatigue, neck stiffness, and limited jaw mobility. Bruxism alone can generate between 50 and 160 pounds of force on the teeth during sleep — causing progressive damage to tooth structure, jaw muscles, and the joint over time.


Left untreated, TMJ dysfunction can accelerate enamel wear, disrupt sleep, and significantly impact quality of life. At our Upper East Side practice, Dr. Lazare takes a comprehensive, conservative-first approach — identifying the root cause of each patient's discomfort before recommending a personalized treatment plan.

Three Targeted Approaches to TMJ Relief

Because TMJ disorders vary widely in cause and severity, Dr. Lazare offers three distinct, complementary treatment options — each addressing a different aspect of the condition for comprehensive, lasting results.


TMJ: Infrared Light Therapy

Using an FDA Class II medical device developed from NASA technology — the only device of its kind on the market — low-level infrared light (810–880 nm) penetrates deep into the jaw joint and surrounding soft tissues. It stimulates cellular repair by energizing mitochondria, reduces inflammation, improves circulation, and relieves TMJ pain at its source. Sessions take just 10 minutes, require no needles or medication, and are available at one of the few offices in NYC to offer this medical-grade therapy.


TMJ: Custom Nightguards

For patients who clench or grind during sleep, a precisely custom-fabricated nightguard protects the teeth and relieves pressure on the TMJ. Unlike over-the-counter devices, Dr. Lazare's nightguards are calibrated to your specific bite — preventing enamel damage, reducing jaw strain, and supporting healthier joint function night after night.


TMJ: EMFACE® Therapy

EMFACE® uses synchronized radiofrequency energy and HIFES™ muscle stimulation to retrain overactive jaw muscles, improve local circulation, and reduce chronic tension in the masseter and surrounding structures. It is a needle-free, 20-minute treatment with no downtime — ideal for patients seeking a non-surgical solution to muscle-driven TMJ discomfort. These treatments can be used independently or in combination, based on each patient's diagnosis and goals.

Fast, Precise Relief for Cold Sore Outbreaks

Cold sores — caused by the herpes simplex virus — can be painful, disruptive, and difficult to manage with topical treatments alone. At Lazare Biomimetic Dentistry & Smile Design, we offer laser cold sore treatment: a fast, clinically proven approach that dramatically reduces healing time and, with early intervention, can prevent a full outbreak from ever developing.


Using a precise dental laser, Dr. Lazare targets the affected tissue to reduce viral activity, alleviate pain, and accelerate the healing process — all in a single, comfortable visit with no anesthesia required. Patients who receive treatment at the very first sign of a tingle often find the sore never fully surfaces. For those prone to recurrent outbreaks, this treatment offers a discreet, effective solution that fits seamlessly into a demanding Manhattan schedule.

When You Need Expert Care Immediately

A dental emergency can happen without warning — a knocked-out tooth, a severe toothache, a cracked restoration, a dental abscess, or acute facial swelling. In these moments, prompt and skilled care is not just important — it can be the difference between saving and losing a tooth.


Dr. Marc Lazare and the team at Lazare Biomimetic Dentistry & Smile Design are experienced in managing a full range of dental emergencies with calm, precision, and efficiency. Our Upper East Side practice prioritizes urgent cases, ensuring patients in pain are seen and treated as quickly as possible — with the same meticulous standard we apply to every procedure.

FAQ — Specialized Dental Treatments NYC

Can TMJ Disorder Be Cured?

Most cases of TMJ disorders can be treated conservatively and successfully. Only a small number of cases require surgical correction, usually with those individuals who have suffered a traumatic injury. The first step is to eliminate the pain and muscle spasms. In mild cases, this can be done with moist heat packs, a non-chewy diet, and muscle relaxants (if necessary). It is also important not to try to test the degree of pain by opening and closing, but rather try to rest the TMJ and give it time to heal. The next step would be to try and become aware of the potential sources of stress and tension that could lead to clenching and grinding. A conservative therapeutic device that may work well for you is a corrective bite plate (made by your dentist), that will help to relax the muscles, thus preventing headaches, pain and spasm.Selective filing of an uneven bite to correct the “high” spots is a final attempt to treat TMJ conservatively, because the removal of tooth structure is an irreversible process.

Why Is a Night Guard the First Method of Treating TMJ Disorder?

While there are more invasive methods available, Dr. Lazare typically suggests beginning TMD treatments conservatively with the use of a night guard. The guard can provide clues as to the patient’s nighttime jaw movements, and will alleviate pain associated with the hard pressure placed on the teeth by acting as a buffer. In many cases, the use of a night guard is sufficient in treating TMD. The added benefit is that a night guard made of a hard material will also keep the teeth in proper alignment, serving as a nighttime retainer.

What Should I Do if My Child’s Baby Tooth Gets Knocked Out (Dental Avulsion of Primary Tooth)?

The first thing you should do is contact your child’s dentist as soon as possible. The baby tooth should not be replanted because it may cause subsequent damage to the developing permanent tooth. Usually this type of injury happens between 7-9 years of age, when the bone surrounding the tooth is softer and more resilient. This means there is less of a chance of a bone fracture around the tooth. Your dentist should then see your child to check and verify that everything else is fine.

What Should I Do if My Child’s Adult Tooth Gets Knocked Out (Dental Avulsion of Secondary Tooth)?

The first thing you should do is try to find the tooth and put it in a cup or baggie with either your own saliva, milk or saline (to keep it hydrated) and bring it immediately to your dentist (Do Not Touch the root of the tooth, handle it by its crown). Time is of the essence. With each minute that passes the chance of reattachment becomes less and less. DO NOT SCRUB the tooth. If you do it will wipe away its outer ligament and prevent its reattachment within your empty tooth socket. If you are in a place where dental care is not accessible, then gently rinse in cool water (no scrubbing or using soap) only if there is dirt on it (otherwise leave it alone), and slowly replace the tooth within the socket immediately and hold it there with gauze. Remember, the faster you act, the better your chances of saving the tooth. Almost all replanted teeth will show some signs of root resorption and ankylosis (where the root fuses with the surrounding bone). It is possible that this may affect one’s bite later on.

What Should You Do When a Tooth Fractures or Gets Chipped?

If a tooth sustains a fracture or chip from a traumatic accident, you should contact your dentist immediately for an x-ray and evaluation. Keep the mouth clean and if there was any trauma to the lip you should apply cold compresses to reduce swelling. If you can’t find any broken tooth fragment, check the lips to make sure the fragment didn’t get imbedded in that area. Simple chips can be smoothed or repaired with tooth colored bonding. A more serious fracture may require root canal therapy (if the nerve is involved) or extraction (if the fracture happens along certain areas of the root surface. Moderate fractures may be bonded for now, and later restored with crowns, veneers or onlays. For children you should try to hold off on these more advanced restorations until your child has completed their growth.

What Causes a Toothache?

A toothache occurs when the nerve within the tooth gets damaged or inflamed. This is usually caused by bacteria from tooth decay communicating with the nerve of the tooth. Cavities (tooth decay) are usually brought about by a combination of poor oral hygiene coupled with eating a lot of sticky, sugary and starchy foods. This bacteria feeds on the sugars and starch left over from poor brushing and flossing. As a result acids are produced that will slowly eat away at the good tooth structure until the nerve becomes damaged, causing the toothache. Another way the nerve can get damaged is from dental trauma (i.e. sports injury, rough play or fights, severe teeth grinding, or extensive dental work on hypersensitive teeth).

Can Cold Sore Laser Treatment Prevent Future Outbreaks?

Yes, laser treatment can help reduce the frequency and severity of future outbreaks. By targeting the virus at its source, the treatment may prevent the cold sore from reoccurring in the same spot.
