Minimally invasive dentistry techniques include:
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.
Sealants: Usually made of plastic resin, dental sealants protect teeth from bacteria that cause decay plus. Sealants fit into the grooves and depressions of the tooth and act as a barrier, protecting against acid and plaque. 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 onlays: Usually dentists use crowns to restore a tooth, but inlays and onlays do not require them to remove as much of the tooth structure. Inlays are similar to fillings except that they are custom-made to fit the cavity in your tooth and are typically the same color as the tooth or gold colored. Onlays are used for more substantial reconstruction and also do not require your dentist to remove as much of the tooth as would a crown.
Bite splints: Many people grind their teeth at night. 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 20s, can be detected and corrected before much damage has been done. Dentists can create bite splints for you to wear at night or during stressful times when most teeth-grinding occurs.
