Summer Diets

  Shedding summer pounds can harm your teeth

With summer just around the corner, many people are dieting and shedding a few pounds before trying on swimsuits and heading to the beach. Actions taken to control your weight may affect more than your suit size, they can put your teeth in danger, reports the Academy of General Dentistry, an organization of general dentists dedicated to continuing dental education.

Crash diets, eliminating meat or fatty foods, appetite suppressants and extreme behaviors such as fasting and binging and purging harm teeth. “People need to be aware of how their dieting actions affect their oral health,” says Heidi Hausauer, DDS, FAGD, spokesperson for the Academy of General Dentistry.

Diet pills may decrease salivary flow and cause dry mouth which is devastating to oral health, says Dr. Hausauer. “Fasting can cause a decrease of necessary minerals, including calcium, and anorexia can lead to a deficiency of vitamins and minerals needed to maintain a healthy body and oral health.”

Diet is an important part of an individual’s medical history, and patients should always inform their dentist and physician if they adhere to a diet plan, dieting behavior or undertake drastic dieting actions. Dr. Hausauer reports the following behaviors and their potential impact on teeth:


























Dieting         Actions Health/Oral Health Implications Dental Advice. What Can Do You?


  • Studies show that a raw food diet bears an increased risk of             dental erosion compared to conventional nutrition.          
  • Strict vegetarians risk deficiencies in calcium, Vitamin D,             Vitamin B-2, vitamin B-12 or complete proteins.          
  • Adults on a vegetarian diet for a prolonged period can increase             their gum disease risk.




  • Consult with a physician or nutritionist.          
  • Learn about food combinations to ensure adequate nutrition needed             to maintain overall health and oral health.          
  • Protect teeth from erosion lesions by brushing with a soft             toothbrush, flossing and rinsing with a fluoride rinse or using a             concentrated fluoride gel.          
  • Take a multivitamin daily.




  • Decreased salivary flow, or dry mouth, especially in middle-aged             patients. Saliva neutralizes plaque acids; without saliva, tooth             decay can occur very quickly.          
  • A decrease in saliva increase risk for cavities, gum disease, oral             candidiasis, and discomfort since foods that are consumed adhere to             teeth longer.




  • Increase water intake, to prevent mouth from drying out.          
  • Increase brushing time and floss at least twice a day to help keep             teeth clean.          
  • Use a regular fluoride toothpaste – whitening toothpastes with             peroxide may be too harsh in a dry environment and can damage the             enamel.          
  • Special toothpastes and saliva substitutes are available for dry             mouth sufferers.




  • Can lead to a deficiency of vitamins and minerals.          
  • Calcium deficiency can result in osteoporosis, a rise in blood             pressure, and oral health problems such as periodontal disease and             eventual tooth loss.          
  • While the tooth enamel is usually formed by age 6, the cementum             and dentin – the tissues inside the tooth – continue to require             calcium throughout adulthood.




  • Eat crunchy foods – the detergent action scrapes plaque off teeth.             A lack of crunchy foods increases the need for more diligent home             oral hygiene procedures.          
  • Take a multiple vitamin daily, including a calcium supplement.          
  • Eat dairy products – it’s the best source of calcium, or try             reaching for low-fat dairy products.          
  • Try other good calcium sources – leafy green vegetables,             calcium-fortified tofu, and the soft bones of fish such as sardines             or salmon.


        Binging and


  • Bulimia is often first discovered by the dentist. Vomiting can             cause the erosion of the backside of the upper front teeth sometimes             within days of the first vomiting episode.          
  • Purging weakens the tooth structure, and brushing immediately             afterward increases enamel wear.          
  • If preventative measures are not taken, the dentin, the softer             inner tooth structure, is affected.          
  • Sugar found in refined carbohydrates such as junk food further             contribute to tooth structure damage.




  • Neutralize stomach acids in the mouth immediately after purging to             help protect teeth.          
  • Instead of brushing right away, the most effective treatment is             rinse with a fluoride rinse.          
  • Use a counter-acting paste, such as baking soda and water, and rub             it on the teeth after vomiting to neutralize the acid. After 30             seconds, rinse the paste off and proceed to brush, floss and use             mouthwash to refresh the mouth.          
  • When that is not possible, rinse the mouth with water after             purging.
