Mission Viejo and South Orange County Laser and Cosmetic Dentistry

The condition of the mouth, the teeth, the gums, the bite, and the smile all dramatically affect a person's health and well-being.

When Dr. Michael Tessier says "cutting edge dentistry for the 21st century," he means it. His patients in Rancho Santa Margarita, Coto de Caza, Ladera Ranch, Mission Viejo, and south Orange County benefit from his cosmetic and laser dentistry experience, as well as from the most recent techniques and treatments. The recent development of the tooth-cutting laser allows him to treat teeth significantly less traumatically than with the drill. His digital X-rays, along with exposing the patient to negligible radiation, allow him to detect decay at a much earlier stage, making for smaller fillings that are less likely to crack teeth. Due to his use of the Biolase MD laser, many, if not most, restorations can be done without local anesthetic (the Novocain™ shot). He doesn't place mercury fillings in teeth; instead, Dr. Tessier uses only the much-more biologically compatible tooth-colored plastic or porcelain restorations. Crowns and caps, and even bridges, are most often fabricated without unsightly metal.

Gum Disease And Health

Current medical research demonstrates that gum inflammation (gingivitis) can have a correlation to heart disease, diabetes, strokes, problems in pregnancy (including low birth-weight), and even pancreatic cancer and general immune insufficiency. Dr. Tessier uses the PerioLase® laser to improve gum health. Healthy gums help preserve teeth and prevent bad breath, and ensure general physiological health.

Invisible Braces

As well as being expert in placing conventional braces to straighten teeth, Dr. Tessier is a certified Invisalign® provider. Invisalign® orthodontics corrects crooked teeth using aligners that are virtually invisible.

Teeth Whitening

For in-office teeth whitening, Dr. Tessier employs Discus Dental's ZOOM!2®. This procedure only takes one hour, and can dramatically whiten teeth up to 8 shades.


In addition to providing his Mission Viejo and Orange County patients with excellent cosmetic and laser dentistry, Dr. Tessier is also skilled in diagnosing and treating temporomandibular joint (TMJ) disorder. When patients' teeth are mal-aligned or if the bite is off, the jaw joint (TMJ) is affected. This can cause muscle pain, headaches, and back and neck problems.

Cosmetic Dentistry

Since 1999 Dr. Tessier has practiced from his state-of-the-art office at Oso and Antonio Parkways. His new location is in close proximity to much of south Orange County, including Ladera Ranch, Coto de Casa, Rancho Santa Margarita, and Mission Viejo. He has a very close, personal working relationship with the specialists in the area, who are some of the best in the world, so that there is virtually no dental situation that cannot be handled to the patient's best welfare.

"Dentistry is not just about teeth anymore. If we keep the mouth healthy, the whole body will remain more healthy."
