Have you ever taken a bite of ice cream or sipped hot coffee only to be met with a sudden jolt of pain in your teeth? If so, you’re not alone.
Tooth sensitivity is a common issue affecting millions of people and while it’s often manageable, it’s not something you should ignore.

What Causes Sensitive Teeth?
Tooth sensitivity usually occurs when the protective enamel on your teeth becomes worn or damaged, exposing the softer layer underneath known as dentin. Dentin contains microscopic channels that lead directly to the nerve of your tooth. When hot, cold, sweet, or acidic foods and drinks come into contact with the dentin, they can trigger pain.
Common causes of enamel loss include:
- Brushing too hard or using a hard-bristled toothbrush
- Consuming acidic foods and beverages
- Tooth grinding (bruxism) or jaw clenching
- Tooth decay or cavities
- Gum recession due to gum disease
- Cracked or chipped teeth
How to Treat Sensitive Teeth
The first step is identifying the underlying cause. Don’t self-diagnose, what feels like routine sensitivity could actually be a symptom of gum disease, a cracked tooth, or a cavity.
Here are some treatment options, depending on severity:
Mild Sensitivity:
- Switch to a toothpaste for sensitive teeth
- Use a fluoride mouthwash
- Brush with a soft-bristled toothbrush
- Avoid trigger foods and drinks
Moderate to Severe Sensitivity:
- Fluoride varnishes or gels to strengthen enamel
- Dental bonding, crowns, or inlays to cover exposed areas
- Night guards for teeth grinding or clenching
- Surgical gum grafts if sensitivity is caused by gum recession
- Root canal therapy (only when other treatments don’t help)
Tooth Sensitivity after a Filling
It’s quite common to experience temporary sensitivity after a dental filling, especially if the cavity was close to the nerve. This usually improves within a few weeks.
However, if the pain increases or lingers beyond that, it’s time to contact your dentist. At Dr. Onisiforou – Art of Advanced Dentistry, we aim to use conservative treatment methods when possible, but if the nerve is affected, a root canal may be necessary to preserve the tooth.
