Understand the Causes of Tooth Sensitivity

Tooth sensitivity is one of the most common dental issues people face—and it’s not something to ignore. That sharp jolt of discomfort when sipping cold drinks or brushing your teeth can interfere with daily life. But what causes it? And more importantly, how can you find relief?

At Meridian Dental Clinic in Kent, WA, we help patients uncover the root causes of sensitivity and provide advanced treatment options. Whether you're dealing with enamel erosion, gum recession, or an underlying infection, our team is here to provide lasting solutions.

What Is Tooth Sensitivity?

Tooth sensitivity, or dentin hypersensitivity, occurs when the protective enamel on your teeth is worn down, or when gum tissue recedes, exposing the softer dentin layer underneath. This dentin contains small channels that lead directly to the nerves of your teeth. When exposed, hot, cold, sweet, or acidic foods can trigger pain.

For some, it’s a mild twinge. For others, it’s enough to avoid certain foods entirely. Either way, it’s a sign your teeth need attention.

Common Causes of Tooth Sensitivity

1. Enamel Erosion

This can result from acidic foods and drinks, excessive brushing, or grinding your teeth. Without enamel protection, your teeth become more vulnerable.

2. Gum Recession

When gums pull back from the teeth due to gum disease, overbrushing, or genetics, the roots of the teeth become exposed, leading to sensitivity.

3. Tooth Decay

Cavities and cracked fillings expose inner layers of the tooth, allowing sensations to reach the nerves.

4. Post-Treatment Sensitivity

You might notice increased sensitivity after professional cleanings, teeth whitening, or fillings. This is usually temporary, but persistent discomfort needs evaluation.

5. Dental Infection

If a tooth is infected, pain and sensitivity may be constant. In such cases, you may require a root canal in Kent WA to eliminate the infection and preserve the tooth.

When to See a Dentist

Tooth sensitivity that lingers for more than a few days or increases in severity should be evaluated by a professional. Our team at Meridian Dental Clinic offers comprehensive exams to identify the exact cause of sensitivity and develop a treatment plan tailored to your needs.

We also accommodate urgent cases, so if you’re searching for a dental clinic for emergencies or a dentist near me in Kent, we’re here for you.

How We Treat Tooth Sensitivity

Desensitizing Toothpaste

This is often the first line of defense. Special toothpastes help block nerve signals to reduce discomfort.

Fluoride Treatments

Professional fluoride applications strengthen enamel and help protect against decay and sensitivity.

Bonding

For exposed root surfaces, we can apply a tooth-colored resin that seals the area and shields it from stimuli.

Periodontal Therapy

If gum disease is the culprit, we offer treatment to stop the progression and restore gum health.

Root Canal Therapy

If decay or trauma has reached the pulp of the tooth, a root canal in Kent WA can eliminate infection and end the pain.

Preventing Sensitivity

• Use a soft-bristled toothbrush
• Avoid acidic foods and beverages
• Brush gently with fluoride toothpaste
• Don’t brush immediately after eating acidic foods
• Get regular checkups with your family dentist in Kent
