SealantsOur teeth are covered with a sticky film of bacteria, called plaque (sounds like PLAK). When we eat or drink anything that contains sugar-such as cookies, candy, soda, juice, or sports drinks-bacteria turn the sugar into acids that can attack tooth enamel. Over time, these attacks may cause tooth decay, or cavities. The good news is that there is a way to protect teeth and prevent decay: dental sealants.
Sealants help prevent tooth decay and cavitiesYour teeth are coated with a sticky film of bacteria, called plaque. Bacteria turn the sugar in what you eat and drink into acids that can break down the hard, outer layer of teeth, called enamel. Over time, the acid can weaken the enamel and may cause tooth decay, or a hole to form in your tooth's enamel (cavity). Tooth decay often begins on the chewing surfaces of the back teeth. These surfaces have pits and grooves where plaque, bacteria and bits of food can get trapped. Just like in the pictures below, toothbrush bristles can't reach into the pits and grooves, and it makes it hard to keep them clean. Your dentist may recommend dental sealants to keep decay from starting on these chewing surfaces in the pits and grooves.
Sealants are smooth and you can't feel them on your teeth. They are usually clear or white and can't be seen when you smile or talk. Sealants can last several yearsSealants usually last several years before they need to be replaced. Over time, sealants can come off, which means they may not protect the teeth as well. Chewing on ice or hard foods can also break down sealants. During regular dental visits, your dentist will check your sealants and reapply them if needed.
You may benefit from sealants at any ageSealants are recommended for children and teenagers, since tooth decay can start soon after teeth come in. But, you never outgrow the chance of tooth decay and cavities, so adults can benefit from sealants, too. A sealant can be placed on a tooth that does not have a cavity in its pits and grooves. If a tooth is stained or has mild decay, your dentist may suggest you get a sealant, or another option may be necessary. If a tooth has more advanced decay, it will need a filling. A sealant can be placed on a tooth that does not have a cavity in its pits and grooves. If your tooth is stained or has slight decay, your dentist may suggest you get a sealant, though other treatment may be necessary. If your tooth has more advanced decay or has a cavity, it will need a filling. Prevention is always better than treatment! Sealants are very useful in preventing tooth decay on the back teeth and can save you money over time. Your dentist can make sealants part of your plan for a healthy mouth.
