What Causes Tooth Sensitivity and How Can You Treat It?

Tooth sensitivity can be really annoying, especially when you can’t enjoy a hot cup of coffee or a cold treat like ice cream. But what exactly causes it, and more importantly, what can you do about it?

What Causes Tooth Sensitivity?

Tooth sensitivity happens when the protective layer of your teeth, called enamel, wears down, or when your gums recede, exposing the underlying dentin. Dentin has tiny tubes that lead to the nerves inside your tooth, which is why you feel that sharp pain when you have something hot, cold, or even sweet.

Here are some of the common causes:

• Brushing too hard: If you use too much pressure or a hard-bristled toothbrush, it can wear down enamel and make your gums recede.
• Teeth grinding: This can wear down enamel over time, leading to sensitivity.
• Gum disease: Conditions like gingivitis can cause gums to pull back, exposing sensitive areas of your teeth.
• Tooth decay or damage: Cavities, cracks, or chips in your teeth can expose nerves and lead to sensitivity.
• Acidic foods and drinks: Consuming a lot of citrus, soda, or energy drinks can erode enamel.
• Dental treatments: Sometimes, treatments like teeth whitening can cause temporary sensitivity.

How Can You Treat Tooth Sensitivity?

The good news is, there are plenty of ways to manage and treat sensitive teeth, depending on the cause:

• Desensitizing toothpaste: These can help block the sensations traveling to the nerves. Rub a small amount on the sensitive area before bed for extra relief.
• Fluoride treatments: A fluoride treatment from your dentist can help strengthen your enamel, protecting it from further sensitivity.
• Gum grafting: If your gums have receded a lot, a dentist might suggest a gum graft to cover exposed roots.
• Dental bonding: A resin can be applied to the sensitive areas to protect them.
• Changing brushing habits: Switch to a soft-bristled toothbrush and use gentle strokes. Overbrushing can make things worse.
• Diet adjustments: Cut back on acidic foods and drinks that wear down enamel, and try to drink water afterwards to wash away any acids.

If sensitivity becomes a persistent problem, it’s always best to visit your dentist. They can check if there are deeper issues and recommend specific treatments based on your situation.
