Plaque is the sticky, colorless film of bacteria that forms on teeth. It makes teeth "feel fuzzy" to the tongue and is most noticeable when teeth are not brushed.

What Causes Plaque and Why Is It Harmful?

Plaque develops when foods containing carbohydrates (sugars and starches) such as milk, soft drinks, raisins, cakes, or candy are frequently left on the teeth. Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay. Plaque can also develop on the tooth roots under the gum and cause breakdown of the bone supporting the tooth.

How Can Plaque Formation Be Prevented?

• Brush your teeth at least twice a day with a soft, rounded-tip bristled toothbrush. Pay particular attention to the space where the gums and teeth meet. Use a fluoride-containing toothpaste.
• Floss between teeth at least once a day to remove food particles and bacteria.
• See your dentist or oral hygienist every 6 months for a check-up and teeth cleaning.
• Ask your dentist if a dental sealant is appropriate for you. Dental sealants are a thin, plastic coating that are painted on the chewing surfaces of teeth to protect them from cavities and decay.
• Eat a balanced diet and limit the number of between-meal snacks. If you need a snack, choose nutritious foods such as plain yogurt, cheese, fruit, or raw vegetables. Vegetables, such as celery, help remove food and help saliva neutralize plaque-causing acids.

There are several reasons why teeth may darken, including:

• Foods/drinks. Coffee, tea, colas, wines, and certain fruits and vegetables (for example, apples and potatoes) can stain your teeth.

• Tobacco use. Smoking or chewing tobacco can stain teeth.
• Poor dental hygiene. Inadequate brushing and flossing to remove plaque and stain-producing substances like coffee and tobacco can cause tooth discoloration.
• Disease. Several diseases that affect enamel (the hard surface of the teeth) and dentin (the underlying material under enamel) can lead to tooth discoloration. In addition, treatments for certain conditions can also affect tooth color. For example, head and neck radiation and chemotherapy can cause teeth discoloration. In addition, certain infections in pregnant mothers can cause tooth discoloration in the infant by affecting enamel development.
• Medications. The antibiotics tetracycline and doxycycline are known to discolor teeth when given to children whose teeth are still developing (before the age of 8). Mouth rinses and washes containing chlorhexidine and cetylpyridinium chloride can also stain teeth. Antihistamines (like Benadryl), antipsychotic drugs, and antihypertensive medications also cause teeth discoloration.
• Dental materials. Some of the materials used in dentistry, such as amalgam restorations, especially silver sulfide-containing materials, can cast a gray-black color to teeth.
• Advancing age. As you age, the outer layer of enamel on your teeth gets worn away revealing the natural yellow color of dentin.
• Genetics. Some people have naturally brighter or thicker enamel than others.
• Environment. Excessive fluoride either from environmental sources (naturally high fluoride levels in water) or from excessive use (fluoride applications, rinses, toothpaste, and fluoride supplements taken by mouth) can cause teeth discoloration.
• Trauma. For example, damage from a fall can disturb enamel formation in young children whose teeth are still developing. Trauma can also cause discoloration to adult teeth.

How Can I Prevent Teeth Discoloration?

By making a few simple lifestyle changes, you may be able to prevent teeth discoloration. For example, if you are a coffee drinker and/or smoker, consider cutting back or quitting all together. Also, improve your dental hygiene by brushing and flossing regularly and getting your teeth cleaned by a dental hygienist every 6 months.

If your teeth appear to be an abnormal color without ready explanation and, if other symptoms are also present, make an appointment to see your dentist.

What Treatment Options Are Available to Whiten Teeth?

Treatment options can vary depending on the cause of the discoloration and may include.

• Using proper tooth brushing and flossing techniques

• Avoidance of the foods and beverages that cause stains
• Bondings
• Veneers
• Using over-the-counter whitening agents
• In-office whitening procedures
