Dental sensitivity is usually felt when eating or drinking something hot, cold, sweet, or sour. In certain cases a breath of cold air may set it off.
The pain is usually sharp and sudden and can shoot deep into the nerve endings of your teeth.
Tooth sensitivity could result from several dental conditions. It usually occurs when the “dentin”, the soft layer making up the inner part of the tooth, becomes exposed. Exposure allows triggers (example hot and cold) to reach the tooth’s nerve centre (pulp) through the thousands of tiny tubes that make up the dentin, resulting in the felt pain.
Exposed dentin may result from exposed roots subsequent to gum disease (gingivitis); worn tooth enamel resulting from tooth grinding or hard tooth brushing; dental cavities especially near the gum line; fractured teeth and defective fillings.
Our dentists will start with a thorough exam to determine the cause of your tooth sensitivity. Accordingly treatment may range between:
- Placing/ replacing a tooth filling
- Providing treatment for your gums to replace tissue loss around the root.
- Applying a fluoride varnish or dentin sealer to the exposed root surface and recommending a desensitizing toothpaste or fluoride gel.
