What and how you eat and drink has a significant impact on the health of your teeth and gums. Therefore, an effective oral hygiene regime must take your diet into account.
Acid is your teeth's enemy; it can erode their protective enamel coating (a process called demineralization). Certain foods and beverages (such as citrus drinks and coffee) contain it, and it's produced by bacteria in your mouth that feed on dietary sugar and release acid as a byproduct (a process called fermentation). Your allies are foods and beverages that neutralize acids, provide minerals and vitamins to repair tooth enamel, and stimulate saliva.
Sugar & Decay
Sugars, the leading promoter of dental decay, exist in many forms in our diet. Some occur naturally, while others — referred to as “free sugars” — are added by the manufacturer, cook or consumer. The latter are most often linked with decay. Soft drinks are the primary source of dietary free-sugars in the U.S.
Sugars in fruit, vegetables, milk and unprocessed, starch-rich foods such as rice, potatoes and whole grains, do not appear to be harmful to teeth. Note, however, that dried fruits contain a highly concentrated sugar level and can stick to tooth surfaces. The sugar substitutes xylitol and sorbitol appear not to promote decay. In fact, there's evidence that chewing xylitol-sweetened gum three to five times daily for at least five minutes (after meals) stimulates saliva flow, which helps protect against decay.
Acids & Erosion
In addition to eroding tooth enamel, acidic foods and beverages create an environment where it's easier for decay-promoting bacteria to flourish. Saliva can reduce acidity but it must have time to work, at least 30–60 minutes. That's why behaviors that maintain acid levels, such as sipping coffee throughout the day, can be harmful.
Saliva is a front-line defense against erosion and decay. It helps remove food particles and contains minerals that help neutralize acid and promote remineralization of the tooth surface. Foods that stimulate saliva and/or contribute essential minerals include:
- Cheese — stimulates saliva and is rich in calcium, contributing to the re-calcification of teeth and protecting against the loss of calcium,
- Cow's milk — contains decay-counteracting calcium, phosphorous and casein,
- Plant foods — are fibrous and require chewing, which mechanically stimulates saliva,
- Water — keeps you hydrated, which is important for saliva production and preventing dry mouth (a condition that promotes acid-producing bacteria), and helps wash away food particles; fluorinated water bestows the protective properties of fluoride (a compound that makes tooth enamel more resistant to acid erosion and promotes re-calcification).
As you can see, brushing and flossing effectively is just part of the oral hygiene equation.

During Nancy O'Dell's interview with Dear Doctor magazine, the former co-anchor of Access Hollywood and new co-anchor of Entertainment Tonight could not resist her journalistic instincts to turn the tables so that she could learn more about a baby's oral health. Here are just some of the facts she learned from the publisher of Dear Doctor about childhood tooth decay, pacifier use and what the right age is for a child's first visit to the dentist.
Many moms-to-be and parents or caregivers of young children are surprised to learn that around age 1 is the ideal time to schedule a child's first visit to the dentist. This visit is crucial because it sets the stage for the child's oral health for the rest of his or her life. It can also be quite beneficial for the parents, too, as they can be reassured that there are no problems with development and that the child's teeth appear to be growing properly. And if by chance we identify any concerns, we will discuss them with you as well as any necessary treatment strategies.
Nancy also wanted to learn more about pacifiers — specifically, if it is a good idea for parents to encourage their use. Obviously, children are born with a natural instinct for sucking, so giving a child a pacifier seems totally harmless. Pacifiers definitely have some advantages; however, if used for too long — past the age of 18 months — they can cause long-term changes in the child's developing mouth (both the teeth and the jaws).
Another problem that parents and caregivers need to be aware of is baby bottle syndrome. This is a condition that develops in children who are perpetually sucking on a baby bottle filled with sugary fluids such as formula, fruit juices, cola or any liquids containing a large amount of sugar, honey or other sweeteners. It is important to note that a mother's own breast milk or cow's milk are good choices for feeding babies, as they both contain lactose, a natural sugar that is less likely to cause decay. However, if these liquids are placed in a bottle and a child is allowed to suck on it throughout the night, they, too, can promote tooth decay. The key is to feed your child properly while avoiding all-night feedings and liquids loaded with sugar.
