The goal of minimally invasive dentistry, or microdentistry, is to conserve healthy tooth structure, It focuses on prevention, remineralizatinn , and minimal dentist intervention

Using scientific advances, minimally invasive dentistry allows dentists to perform the least amount of dentistry needed while never removing more of the tooth structure than is required to restore teeth to their normal condition. In minimally invasive dentistry, dentists use long lasting dental materials that conserve the maximum tooth structure so the need for future repairs is reduced.

How does it work?
Your risk for tooth decay is evaluated.  The presence of bacteria, quality and quantity of saliva, and your diet are all contributors to decay.  The treatment plan will be so geared to correct any of these destructive factors.

Techniques used-
Remineralization:
Remineralization is the process of restoring minerals.  Remineralization can repair the damage created by the demineralization process. Fluoride plays a very important role in remineralization.

Air Abrasion:
When a tooth cannot be remineralized and decay is present, air abrasion may be used instead of the traditional drill and may not require anesthesia.  It resembles microscopic sand blasting and uses a stream of air combined with super-fine abrasive powder.

Sealants:
Usually made of plastic resin, dental sealants protect teeth from bacteria that cause decay. Sealants do not require any cutting of the tooth and can be placed on teeth that might be susceptible for decay at any time.

Inlays and Inlays:
Inlays and onlays do not require removal of as much tooth structure as full Coverage restorations.

Bite Splints:
Grinding or bruxism may cause serious damage to the teeth and may require you to need crowns. Grinding which often begins in your teenage years or early 20's, can be detected and corrected before much damage has been done.
