Have you ever taken a sip of cold water or bitten into an ice cream and felt a sudden sharp pain in your teeth?
Tooth sensitivity is something many people experience. For some, it’s an occasional discomfort, while for others, it can make everyday things like eating, drinking or even brushing uncomfortable.
Although sensitive teeth are common, there are several possible reasons behind them. Understanding what’s causing the sensitivity is important, particularly if it’s becoming more frequent.
Here are five common causes worth knowing about.
1. Brushing Too Hard
Brushing harder doesn’t necessarily mean you’re cleaning your teeth better.
Using too much pressure or a hard-bristled toothbrush can contribute to gum recession and wear around the necks of your teeth over time.
When the underlying dentine becomes exposed, hot, cold or sweet foods may trigger sensitivity.
Try using a soft-bristled toothbrush and gentle circular movements. An electric toothbrush with a pressure sensor can also help if you tend to brush too firmly.
2. Receding Gums
Your gums help protect the roots of your teeth. When they recede, part of the root surface can become exposed.
Unlike the crowns of your teeth, root surfaces aren’t covered by enamel, making them more vulnerable to sensitivity.
Gum recession can develop for several reasons, including gum disease, brushing habits and changes that occur over time.
If you’ve noticed your teeth looking longer or feeling sensitive near the gumline, it’s worth having your gums checked.
3. Grinding or Clenching Your Teeth
Many people grind or clench their teeth without realising it, particularly while sleeping.
Over time, grinding can contribute to tooth wear, small cracks and sensitivity. Some people may also notice jaw discomfort or headaches when they wake up.
If your dentist notices signs of grinding, they may recommend a custom-made nightguard to help protect your teeth.
4. Worn or Damaged Tooth Enamel
Enamel is the protective outer layer of your teeth. Although it’s strong, it can gradually wear down.
Frequent exposure to acidic foods and drinks, such as soft drinks, citrus fruits and sports drinks, can contribute to enamel erosion.
As enamel becomes thinner, the underlying dentine may become more sensitive.
Reducing how frequently you consume acidic drinks, choosing water more often and avoiding brushing immediately after acidic foods can help reduce further wear.
5. Tooth Decay, Cracks or Old Fillings
Sometimes, sensitivity is a sign of a problem affecting an individual tooth.
A cavity, cracked tooth or deteriorating filling can allow hot, cold or sweet foods to irritate the tooth.
If the sensitivity is limited to one tooth, lasts for a while after eating or drinking, or causes pain when biting, it’s important to have it examined.
Depending on the cause, treatment may involve a filling, crown or other dental care.
What Can You Do About Sensitive Teeth?
If your teeth have recently become sensitive, there are a few things you can try at home:
- Use a toothpaste specifically designed for sensitive teeth.
- Brush gently with a soft toothbrush.
- Avoid frequently sipping acidic or sugary drinks.
- Continue cleaning between your teeth daily.
- Arrange a dental appointment if the sensitivity persists or worsens.
Desensitising toothpaste can help with some types of sensitivity, but it won’t fix problems such as cavities or cracked teeth.
If you’re experiencing severe pain, swelling or lingering sensitivity, don’t delay having it checked.
