Tooth decay (also called tooth cavities) is the destruction of tooth structure. It can affect both the enamel (outer layer) and the dentin layer (inner layer) of the tooth. Tooth decay is the most common reason for loss of teeth and it affects almost every human being at some point in their lives. Tooth decay is also the second most common disease in the U.S. (the common cold is first). Luckily, with good oral hygiene tooth cavities can be easily prevented.
It is quite normal for bacteria to be present in the oral cavity. Certain types of bacteria are able to attach to hard surfaces in the mouth like the enamel that cover the teeth. If these bacteria are not removed, they are able to multiply and grow in number until a colony forms. Proteins that are present in the saliva also mix in and the bacteria colony becomes a whitish film (called plaque) on the surface of the enamel.
These bacteria feed on sugars and starches from the food like chocolates, sticky sweets, ice cream, milk, cakes, and even fruits, vegetables and juices, producing acid as a byproduct. This acid then erodes the tooth enamel slowly dissolving the tooth. A cavity is formed causing a hole or break in the tooth structure. If not fixed at this stage, the tooth decay can progress further reaching the dentin where it can spread even quicker. The cavity can progress very quickly after entering the dentin. This can lead to a larger issue of a dental abscess if untreated.
Unfortunately for the patient, this process moves very slowly so there may not be any pain or tooth sensitivity until the cavity becomes quite big.
Tips For Preventing Tooth Decay
-Maintain a routine of dental hygiene. This is a necessity to prevent tooth decay. A good dental hygiene program includes regular visits to dentist for dental examinations and professional cleanings, brushing at least twice a day (with a fluoride containing toothpaste), and flossing at least once a day. You should especially remember to brush before bed. Food can get stuck in between our teeth when we eat. If the food particles are not removed, it can lead to tooth decay. Flossing at least once a day is the best way to remove food from in between the teeth.
-Eat well balanced nutritious meal and limit snacking. Stay away from carbohydrates such as candy, pretzels and chips. These can remain on the tooth surface. If sticky foods are eaten, brush your teeth soon afterwards. Eating fruits and vegetables for snacks and limiting the amount of sugary drinks and foods will help to prevent plaque from forming on the teeth.
-Supplemental Fluoride. Fluoride can strengthen your teeth. Your dentist may recommend a daily fluoride rinse (ACT anticavity rinse is an example) as part of your dental hygiene. This will help in cavity prevention.
-Dental Sealants. These can prevent some tooth decay. Sealants are ultra thin coatings applied to the top (chewing) surfaces of the molars. This coating helps prevent the build up of plaque in the deep grooves on these molars. Sealants are generally applied on the children's teeth soon after the molars erupt into the mouth. Adults can also benefit from the use of sealants if they have a high risk for decay or have deep grooves in the molars and premolars.
-Antiseptic Mouth Rinse. There are several antiseptic mouth rinses on the market that have been clinically proven to reduce plaque. These include Listerine or Crest Pro Health. Rinsing with either of these mouth rinses after brushing or eating can help in cavity prevention. They work by reducing the number of bacteria present in mouth as well as acting as a rinse to wash away plaque and film on teeth.
-Sugarless Gum. Chewing sugarless gum will help prevent tooth decay by stimulating salivary flow. In studies xylitol has shown to temporarily slow down the growth of bacteria that causes tooth decay. There are several brands of xylitol gum including epic, wrigley's, and trident.
To reduce tooth decay, eating less sugar, regular cleaning and flossing are all needed to keep the bacteria that causes tooth decay from getting out of control. Tooth decay is preventable and treatable in most stages. Diligent dental hygiene along with regular dental visits will keep you cavity free!
