Minimally invasive dentistry adopts a philosophy that integrates prevention, remineralization and minimal intervention for the placement and replacement of restorations. Minimally invasive dentistry reaches the treatment objective using the least invasive surgical approach, with the removal of the minimal amount of healthy tissues. A carious dental lesion is the result of bacterial infection. Restoration of the tooth does not cure the disease. Acids produced by bacteria as metabolized sugars and cooked starches continue to demineralize tooth structure. Initial lesions occur beneath the enamel surface and can be repaired largely by ingress of salivary calcium, phosphate and fluoride ions. A balance between demineralization and remineralization inhibits progression of theRead More
HOW DOES IT WORK?
First your dentist will evaluate your risk for tooth decay. The presence of bacteria, quality and quantity of saliva, and your diet are all contributors to decay. Your dentist will then use strategies to prevent or reduce your risk for tooth decay. For instance, if you have a high level of oral bacteria, you might be advised to use mouthwash daily, limit the intake of certain carbohydrates, and practice good oral hygiene.
WHICH TECHNIQUES ARE 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, your dentist may use air abrasion to remove the decay. Air abrasion is used instead of a traditional drill and may not require anesthesia. It resembles microscopic sand blasting and uses a stream of air combined with a super-fine abrasive powder.
- Sealants: Usually made of plastic resin, dental sealants protect teeth from bacteria that cause decay. 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.
