Anorexia and bulimia can lead to a lot of tooth erosion and cavities. Your dentist may recommend that you talk with your healthcare professional to see if GERD is causing your enamel loss. This exposes more of the dentin to bacteria, creating tooth decay. It can wear away the enamel of your teeth and cause a lot of damage. Heartburn, a common symptom of gastroesophageal reflux disease (GERD), can cause stomach acid to flow into your mouth. Dental devices can stop fitting well, allowing decay to begin under them. This allows plaque to build up more easily and makes it harder to remove. Over the years, dental fillings can weaken, begin to break down or get rough edges. Certain medicines, some medical conditions, radiation to your head or neck, or certain chemotherapy drugs can raise your risk of cavities by reducing saliva production. Substances found in saliva also help counter the acid produced by bacteria. Saliva helps prevent tooth decay by washing away food and plaque from your teeth. Older adults also may use more medicines that reduce saliva flow, raising the risk of tooth decay. Over time, teeth can wear down and gums may recede, making teeth more likely to decay. In the U.S., cavities are common in very young children and teenagers. But bottled water usually does not contain fluoride. It's also a common ingredient in toothpaste and mouth rinses. Because of its benefits for teeth, fluoride is added to many public water supplies. It also can reverse the earliest stages of tooth damage. Fluoride, a naturally occurring mineral, helps prevent cavities. If you don't clean your teeth soon after eating and drinking, plaque forms quickly, and the first stages of decay and gingivitis can begin. Similar damage can occur when toddlers wander around drinking from a sippy cup filled with these beverages. This damage often is called baby bottle tooth decay. This feeds bacteria that can cause decay. When babies are given bedtime bottles filled with milk, formula, juice or other liquids that have sugar, these beverages remain on their teeth for hours while they sleep. And sipping soda or other acidic drinks throughout the day helps create a continual acid bath over your teeth. When you snack or sip sugary drinks a lot, you give mouth bacteria more fuel to make acids that attack your teeth and wear them down. These foods include milk, ice cream, honey, sugar, soda, dried fruit, cake, cookies, hard candy and mints, dry cereal, and chips. Foods that cling to your teeth for a long time are more likely to cause decay than foods that are easily washed away by saliva. That's why they're harder to keep clean than your smoother, easy-to-reach front teeth. These teeth have lots of grooves, pits and crannies, and multiple roots that can collect food particles. Decay most often occurs in your back teeth - your molars and premolars. Sometimes pain and damage can spread outside of the tooth root to the bone, causing bone loss around the tooth and even reaching nearby teeth.Īnyone who has teeth can get cavities, but these factors raise the risk: Because there is no place for the swelling to expand inside of a tooth, the nerve becomes pressed, causing pain. The pulp becomes swollen and irritated from the bacteria. As tooth decay happens, the bacteria and acid move through your teeth to the inner tooth material (pulp) that contains nerves and blood vessels. This layer is softer than enamel and less resistant to acid, causing your teeth to be more sensitive. Once areas of enamel are worn away, the bacteria and acid can reach the next layer of your teeth, called dentin. This erosion causes tiny openings or holes in the enamel - the first stage of cavities. The acids from bacteria remove minerals in your tooth's hard, outer enamel. A dental professional needs to remove this plaque. Tartar makes plaque harder to remove and creates a shield for bacteria. Plaque that stays on your teeth can harden under or above your gumline into tartar. When you don't clean sugars and starches off your teeth, bacteria quickly begin feeding on them and forming plaque. It's due to eating a lot of sugars and starches and not cleaning your teeth well. Dental plaque is a clear sticky film that coats your teeth.
