Aggressive Tooth Brushing and Sensitivity

One in 3 dentists say that ag­gressive tooth brushing is the most common cause of sensitive teeth, according to a na­tionwide member survey conducted by the AGD, and acid­ic food and beverage consumption was found to be the second. Dentin hypersensitivity is a common oral condition af­fecting approximately 40 million Amer­i­­cans of all ages. The survey also re­vealed several other factors that can cause tooth erosion and contribute to the oral condition. These factors in­clude certain toothpastes and mouthwashes, tooth-whit­­­ening products, broken or cracked teeth, bu­limia, and acid reflux. Out of the nearly 700 general dentists who re­sponded to the survey, nearly 60% say that the frequency of tooth erosion has increased com­pared to 5 years ago. An important key to preventing dentin hypersensitivity is to detect tooth erosion in its early stages. “Dis­coloration, tran­s­parency, and small dents or cracks in the teeth are all signs of tooth erosion and should be discussed with your dentist as soon as possible,” said Ray­mond K. Martin, DDS. 

Fifty-six percent of dentists surveyed say that pa­tients manage tooth sensitivity by avoiding cold foods and beverages. Another 17% of dentists surveyed say that pa­tients avoid brushing the sensitive area of the mouth. 

For those patients who are already affected by sensitive teeth, the AGD recommends these actions to help alleviate symptoms: 

1. Switch to a desensitizing tooth­paste. There are many brands of toothpaste made specifically for sensitive teeth. 

2. Use a soft-bristled toothbrush. When you use a hard-bristled toothbrush, you may be wearing away the enamel on your teeth or causing your gums to recede. 

3. Practice good oral hygiene. Floss regularly and brush at least twice a day for 2 to 3 minutes. Hold your toothbrush at a 45° angle, brush gently in a circular motion, and hold the toothbrush in your fingertips rather than in the palm of your hand. 

4. Avoid highly acidic foods and beverages. Make a conscious effort to limit your in­take of highly acidic foods and beverages every day.
