What Is Laser Tooth Desensitization?
Tooth sensitivity can range from a mild nuisance to a condition that significantly affects quality of life. Sharp pain triggered by hot, cold, sweet, or acidic foods and drinks is often caused by exposed dentin, receding gums, worn enamel, or micro-cracks in the tooth surface. Laser tooth desensitization offers a fast, non-invasive way to reduce or eliminate this sensitivity by sealing the microscopic tubules in the dentin that transmit pain signals to the nerve.
Laser Tooth Desensitization: Quick Facts
Quick fact | Typical answer |
|---|---|
Number of visits | 1 to 2 |
Time needed | A few minutes per tooth |
Anesthesia | None |
Recovery time | None |
How long it lasts | Months or longer; can be repeated |
These are typical ranges. Your own plan is confirmed after an examination.
Signs Laser Desensitization May Help
Sensitivity happens when the microscopic tubes in dentin are open to the mouth, so cold, heat or sweetness reaches the nerve. Laser treatment seals those tubes and calms the nerve response.
A short, sharp pain with cold drinks or cold air
Sensitivity at the gumline where gums have receded
Sensitivity after whitening
Discomfort during cleanings
No improvement after several weeks of sensitive toothpaste
Laser Tooth Desensitization at Bensonhurst Dental Care
At Bensonhurst Dental Care, laser desensitization is provided by Dr. Alex Rubinshtein. The procedure involves directing low-level laser energy onto the sensitive tooth surfaces. The laser seals the open dentin tubules and stimulates a biological response that reduces nerve sensitivity. The treatment is quick, painless, and requires no anesthesia. Many patients notice an immediate reduction in sensitivity, with continued improvement over the following days.
What to Expect, Step by Step
Diagnosis. We rule out decay, cracks and bite problems, which need different treatment.
Cleaning. The sensitive surfaces are cleaned.
Laser application. Low-level laser energy is applied to each area for a minute or two.
Test. The tooth is tested with air or cold.
Repeat. A second session is arranged if needed.
Treatments for sensitive teeth
Treatment | How it works | How long relief lasts |
|---|---|---|
Desensitizing toothpaste | Blocks tubes gradually with daily use | While you keep using it |
Fluoride varnish | Strengthens and coats the surface | Weeks to months |
Laser desensitization | Seals tubes and calms the nerve | Months or longer |
Bonding or gum graft | Covers the exposed root | Long term |
Sensitivity is a symptom. The first job is to find out why the dentin is exposed, and the second is to cover it.
Recovery and Aftercare
After laser treatment
The first 24 hours
Eat and drink normally
Avoid very acidic food and drink for a day
Brush with a soft brush
The following days
Use a sensitive toothpaste and do not rinse it away after brushing
Brush gently; scrubbing causes recession
Limit acidic drinks such as soda, citrus juice and sports drinks

When Laser Desensitization Is Used
Laser desensitization is a valuable option for patients whose sensitivity has not responded adequately to desensitizing toothpaste or in-office fluoride applications. It is also beneficial for patients experiencing sensitivity after dental procedures such as cleanings, whitening, or crown preparation. For patients whose sensitivity is related to gum recession, addressing the underlying cause with gum grafting may be recommended in conjunction with or as an alternative to desensitization treatment.
Cost and Insurance
Laser treatment is priced by the procedure, not by the use of the laser itself. You are told the fee before treatment.
What affects the cost
The procedure being carried out
The number of teeth or areas treated
The number of sessions needed
Whether the laser is used alone or alongside another treatment
Insurance usually covers a laser procedure in the same way as the conventional version of that procedure. Therapy sessions for pain relief may not be covered. Our team can check your benefits and explain your options before treatment begins.
