Why Are My Teeth So Sensitive? Common Causes and Solutions

Have you ever cringed at the first sip of a cold drink or winced when you bit into something sweet? If so, you’re not alone. Tooth sensitivity is a common issue affecting millions of people, but just because it’s common doesn’t mean you should ignore it.

Understanding Tooth Sensitivity

Tooth sensitivity usually occurs when the protective layers of teeth become compromised, exposing the underlying dentin. Tiny tubules in the dentin connect to the tooth’s nerve centre.

When these tubules are exposed to temperature changes, acidic foods, or even air, they send a signal to your nerves, causing that sharp, uncomfortable sensation.

But what causes this sensitivity in the first place? Here are some common culprits:

Tooth Enamel Erosion

The firm, protective covering that covers your teeth to safeguard them from everyday wear and tear is called tooth enamel.

But over time, a number of things, including acidic meals and beverages, vigorous brushing, and even tooth grinding, can cause enamel to deteriorate.

Once the enamel is worn down, your dentin becomes exposed, leading to increased sensitivity.

Protecting your enamel is key to reducing sensitivity. Use a soft-bristled toothbrush and fluoride toothpaste designed for sensitive teeth. Additionally, avoid brushing too hard, and consider using a mouthguard if you grind your teeth at night.

Gum Recession

Your gums are essential for shielding your teeth’s roots. When your gums recede, whether due to gum disease, aggressive brushing, or natural aging, the roots of your teeth become exposed.

Since the roots of your teeth are not covered in enamel like the crown, they are far more susceptible to changes in temperature and certain foods.

Gum recession can be mainly avoided by practising good dental hygiene. Gum health also depends on brushing, flossing, and routine dental check-ups.

If gum recession is already a problem, your Casula dentist can suggest gum graft surgery or scaling and root planing to protect the exposed roots.

Cracked or Chipped Teeth

A cracked or chipped tooth can cause sudden, sharp sensitivity. The crack can extend to the dentin, exposing the nerve centre to external stimuli.

Sometimes, these cracks are so small that you might not even see them, but you’ll feel the sensitivity.

If you suspect a cracked or chipped tooth, seeing your dentist as soon as possible is essential. If the fracture continues into the pulp, they can assess the damage and suggest suitable treatment, including bonding, a crown, or a root canal.

Tooth Decay

Cavities and tooth decay are among the most common causes of tooth sensitivity. When bacteria break down the enamel, they create holes or cavities that expose the dentin. This exposure allows external stimuli, like cold or sweet foods, to reach the nerves, causing sensitivity.

Routine dental cleanings and examinations must avoid cavities. Your Casula dentist must also remove decay and fill cavities to preserve the tooth and reduce sensitivity.

Recent Dental Work

Sometimes, dental procedures like fillings, crowns, or teeth whitening can cause temporary sensitivity. This is usually due to the irritation of the nerve during the procedure. While this type of sensitivity typically subsides within a few days or weeks, it can still be uncomfortable.

If you’ve recently had dental work done and are experiencing sensitivity, talk to your dentist. They may recommend desensitising toothpaste or a fluoride treatment to help ease the discomfort.

Brushing Too Hard

Brushing your teeth enthusiastically is the best way to keep them clean, but overly vigorous brushing might damage your enamel and cause your gums to recede. Over time, both of these problems may result in heightened sensitivity.

Switch to a soft-bristled toothbrush and focus on gentle, circular brushing motions. The pressure you apply is not essential, but your technique is. This simple change can make a big difference in protecting your teeth and reducing sensitivity.

Acidic Foods and Drinks

Over time, acidic foods and beverages can destroy your enamel. As the enamel wears down, your teeth become more sensitive to temperature changes and other external factors.

Reduce the amount of acidic drinks and foods you consume, and then rinse your mouth with water to counteract the acids. Chewing sugar-free gum is another technique to increase salivation, naturally cleaning away acids from your teeth.

Grinding Your Teeth

Bruxism (teeth grinding) is a typical problem at night. This behaviour may erode tooth enamel and increase sensitivity. The constant pressure and friction can cause microcracks in teeth, leading to further sensitivity.

If you grind your teeth at night, use a nightguard to keep your teeth safe. Your dentist can custom-fit one for you, ensuring maximum comfort and protection.

Age

As you age, your gums naturally recede, and your enamel gradually wears down, which can lead to increased sensitivity. Even though growing older is a normal process, there are things you can do to keep your teeth safe and reduce sensitivity.

As you age, routine dental check-ups, proper oral hygiene, and a diet high in calcium and other vital nutrients can help maintain strong teeth and less sensitivity.

When to See a Dentist

While occasional tooth sensitivity can be expected, persistent or severe sensitivity could indicate a more serious underlying issue. If you’re experiencing ongoing discomfort, it’s essential to consult your dentist. They may assist in determining the underlying reason for your sensitivity and suggest the most effective treatment method.
