A partial denture is a removable dental appliance that replaces multiple missing teeth. It can be attached to the teeth with clasps, which are like small metal “c” clamps that hug nearby teeth, or may be attached to teeth with crowns with precision attachments (hidden clasps). Both types typically have a metal framework and plastic teeth and gum areas. A temporary partial dental may have a plastic base with no metal.
How a Cavity Forms
A molar with 2 cavitiesA cavity is a very small hole that forms on the surface, side, or root of a tooth. Cavities are caused when sugars in the food you eat combine with the bacteria in your mouth. This combination produces a mild acid that eats away at the enamel, the hard outer layer of your tooth. Cavities can occur at any age, but most occur during childhood when dental hygiene may be less thorough. There is a genetic component to dental health, including teeth, gums, and the bone that holds the teeth. No matter how good your genes are, if you don’t take good care of your teeth you may be prone to very serious consequences.
Babies tend to get cavities on the front teeth, especially if they are given a bottle to sleep with. Even milk contains sugar that can harm teeth. This is referred to as baby bottle tooth decay. Children tend to get cavities on the chewing surfaces as well as in-between teeth. Adults can be at risk for both new and recurrent cavities.New cavities tend to form between teeth as well as on the root surfaces. The cavities that form between teeth are typically related to a lack of flossing. Cavities on the root surfaces of teeth generally occur because this area is not covered with enamel and is softer and more prone to cavities. The exposed root may be the result of hard brushing or bone loss related to gum disease. Cavities that reoccur form next to existing restorations such as fillings, crowns, bridges, etc. As restorations get old, the filling material can shrink or wear away, causing the possibility of a small space forming between the tooth and the restoration. This provides a prime area for bacteria to accumulate and breed decay. Click the link to do an experiment with fluoride to see how it helps fight cavities.

Cavities and Restoration Choices
As part of any visit to our office, we check all of your restorations such as crowns, fillings, bridges, veneers, etc. for any sign of decay or old age and we may recommend x-rays so that we can see inside and between your teeth. If we spot any cavities, we will recommend different options for restoring the tooth to full function. If the cavity is in the very early stages, we may decide to keep an eye on it and recommend a home fluoride rinse to help the tooth fight the cavity and possibly prevent the need for a restoration.
