Treatment of dental cavities
Avoid snacks, sweet and acidic foods, brush your teeth after each meal… Even with strict observance of the dental hygiene that reduces the formation of a dental deposit, a few people will never have dental caries… By the way, it is one of the ten most common chronic diseases. For its treatment, first remove the hard tissues of the tooth affected by bacteria, then fill the cavity to give the tooth to its original shape. Depending on the size and location of dental caries, maybe offered various solutions. The choice will be made taking into attention the quality of fillings, durability, aesthetics, and of course, the cost which can vary greatly depending on the preferred option.
Small dental caries in the molar tooth: composite or amalgam?
Previously used only for front teeth, composite resin of enamel color is increasingly used for posterior teeth. This paste of quartz particles, silicon, and zirconium, perfectly fills the tooth cavity. New composite materials are more durable, but sometimes over time, they may change the color…
Is it necessary to beware of amalgam containing mercury?
Some dentists still use a gray amalgam. Amalgam also called “dental filling” is composed of an alloy of silver, tin, copper and zinc with mercury additive mixed to obtain a gray paste. It has the advantage that it is very durable and has anti-caries properties. The mercury contained in it is potentially harmful to the body… but it is very difficult to estimate a level of the risk. As a precautionary measure, it cannot be applied either in the case of pregnant or breastfeeding women and those with allergies to any of its ingredients, or close to other metal fillings or crowns, in order to avoid electrochemical corrosion.
We recommend our patients to remove amalgam because it doesn’t only contain toxic for the organism mercury, but in addition, after several years in the mouth it can cause a crack in the teeth.
Since spraying mercury occurs mainly during filling and removal of amalgam fillings, we use a special mask and powerful suction device specially adapted for the removal of dental amalgam.
Big dental caries in the molar tooth: inlay or onlay
When the cavity is large (repeated caries, etc.), your dentist can rebuild a tooth with a small block of a composite, ceramics or gold, made in the laboratory and then inserted into the cavity. This requires removing the casts and two visits dentist. Inlay is a small block which, is installed inside the tooth. Onlay is a “partial crown”. It is used when it is necessary to cover part of the damaged tooth.
Dental caries under the crown: a new crown or removing
Bacteria can appear at the junction with the gums and destroy the tissue under the crown, usually without causing pain because the tooth is not sensitive. In this case, the dentist must remove the crown, to assess the damage, cure dental caries, and then reinstall the crown. It is possible to use the same, if it is still suitable otherwise it is necessary to make a new one. If the tooth is overly spoiled, it must be removed. In its place, you can install an implant, which is inserted directly into the bone instead of root to support the prosthesis.
Dental caries touching the nerve: removing the nerve, and composite/crown
When dental caries affect the “nerve”, it must be removed. The dentist removes the pulp, disinfects the root, and then closes the channel by sealing material. In most cases, a crown should be fixed on such a weakened tooth. Metal crowns from chromium-nickel, chromium-cobalt or yellow gold are relatively inexpensive. Ceramic crowns with a metal or ceramic basis are more aesthetic, long-lasting and also minimize the risk of allergies.
Dental caries in the baby tooth: glass ionomer
A modern alternative to composite is glass ionomer cement, continuously emitting fluoride that can help prevent the development of caries. Since they are not durable, they used primarily for baby teeth.
Fluoridated toothpaste (dosage of <600 ppm up to six years and then from 1000 to 1500 ppm) is used to prevent tooth decay. In case of high-risk, the dentist may prescribe using a mouthwash, gel, varnish or tablets with fluoride.
Dental caries in the front tooth: composite, veneer or the crown
When the caries is small the tooth is covered with a composite that must be replaced after a few years, if the color change. In the case of large caries, the tooth can be covered with ceramic veneers (for a period of 10-12 years), to obtain a beautiful smile. When the root is touched, it is necessary to remove the nerve and to install a crown on the tooth.
Do you know that for prevention it is possible to cover the grooves of teeth?
80% of dental caries appears in the depth grooves on the upper surfaces of large and small teeth. Immediately after the appearance of permanent molars (about six years and 12 years), it is recommended put on their protective grooves fluorinated polymer. If necessary, the coating can be updated.
