Dr. Gordon Scott’s tips for sensational — not sensitive — teeth


Regular oral health care is an important part of maintaining overall body health. Acting quickly on common tooth issues such as tooth sensitivity will keep teeth looking and feeling great.

To ensure Canadians keep teeth in good condition, Dr. Gordon Scott, a Canadian dentist with over twenty-five years’ experience, explains the ABC’s of
tooth sensitivity:

What causes tooth sensitivity?

Tooth sensitivity occurs when dentin and/or root surfaces are exposed, which contain tiny tubules and pores. The sharp pain of sensitivity occurs when the dentin or root surfaces are exposed and there is fluid movement within the pores. The following factors cause dentin and root exposure, resulting in sensitivity:

  • Aggressive tooth brushing

  • Teeth grinding

  • Brushing incorrectly

FACT: It is when the enamel is reduced, exposing the dentin, or root surfaces open due to gum recession, that sensitivity will occur when ingesting hot, cold or acidic food and beverages.

How to treat tooth sensitivity?

Beyond regular visits to the dentist to determine the cause of the sensitivity, there are steps that can be taken to reduce tooth sensitivity including:

  • Use a toothbrush designed for sensitive teeth with soft bristles that will not wear down tooth enamel and exposed root surfaces

  • Use toothpaste specially designed to reduce tooth sensitivity as the ingredients will help seal exposed pores in dentin and root surfaces

  • Brush teeth as advised by an oral health care professional

  • Speak with a dentist for ways to minimize and avoid clenching or grinding teeth

What are the steps to maintaining strong, sensational teeth?

  • Use toothpaste with baking soda — they are often less abrasive, dissolving easily in water and working gently on soft tissues like those found in the mouth. The ARM & HAMMER Pro SensitiveTM toothpaste line has a variety of different pastes — from whitening to freshening and multi-protection — to meet a patient’s individual needs.

  • Brush teeth three times each day

  • Look for toothpaste with Potassium Nitrate to reduce sensitivity and fluoride in the ingredients, as it will help protect against cavities
