Sudden tooth sensitivity can take even the most diligent brusher by surprise, leaving you wondering what’s causing the discomfort. For many, this sensitivity can be a signal from your teeth that they may need some attention.
Sensitive teeth are common for many reasons, but several causes of sudden tooth sensitivity include:
- Dietary changes
- Gum infection or injury
- Recent dental work
- Hidden cavities or decay
- Seasonal changes
During a dental exam, your dentist can help determine the possible causes and what you can do about it.
What Is Tooth Sensitivity?
Tooth sensitivity, or dentin hypersensitivity, is a common dental concern that causes sharp or discomforting pain in response to certain triggers. These triggers typically include hot, cold, sweet, acidic foods and beverages, and sometimes even cold air.
Discomfort or sensitivity can happen when the outer protective layers of your teeth or enamel wear down or are compromised, exposing the sensitive dentin layer underneath. The dentin layer consists of tiny tubules that lead to the nerve endings inside your tooth, which can react strongly to stimuli.
Common Causes of Tooth Sensitivity
Tooth sensitivity can stem from various factors, including:
- Tooth decay: Cavities create vulnerable spots that can lead to sensitivity.
- Worn enamel: Over time, acid erosion or aggressive brushing habits can wear down enamel.
- Gum recession: When gums pull away from teeth, they expose the roots, which lack enamel protection.
- Teeth grinding (bruxism): Grinding your teeth can wear down the enamel and expose sensitive dentin.
- Whitening products: Overuse of whitening strips or toothpaste can irritate your teeth.
- Dental damage: Cracks or chips can make teeth more exposed and sensitive.
Causes of Sudden Tooth Sensitivity
You’re going about your day, enjoying your favourite foods, and suddenly, ouch—a twinge of pain. Tooth sensitivity that seems to come out of nowhere often has a specific trigger or recent event that causes it. Some common factors can include:
- Dietary changes: Acidic foods like citrus fruits, vinegar, or carbonated drinks can weaken enamel.
- Gum infection or injury: Recently inflamed or damaged gums can cause sudden sensitivity.
- Recent dental work: Procedures like fillings, root canals, or teeth cleanings may temporarily irritate your teeth and cause sensitivity.
- Hidden cavities or decay: Sensitivity could be the first sign of hidden dental issues you may not yet see or feel otherwise.
- Seasonal changes: Cold winter air can make your teeth more reactive.
If you’ve noticed sudden sensitivity, pinpointing recent changes in your lifestyle or habits can often provide clarity and help you take the next steps.
Home Remedies for Tooth Sensitivity
If the discomfort is manageable, there are a few things you can do at home to reduce sensitivity, such as:
- Use desensitizing toothpaste: Brands like Sensodyne can block nerve signals and provide relief over time.
- Practice gentle brushing techniques: Use a soft-bristled toothbrush, and don’t press too hard while brushing.
- Rinse with fluoride mouthwash: Fluoride can strengthen enamel and reduce sensitivity over time.
- Avoid triggers: Avoid very hot, cold, or acidic foods and drinks.
- Saltwater rinse: Rinsing with warm salt water can soothe inflamed areas of your gums and teeth.
While these remedies can help, they’re not substitutes for underlying dental care.
When to Visit the Dentist
Home remedies work for mild sensitivity, but there are times when it’s crucial to consult your dentist. It’s time to make an appointment if:
- The sensitivity persists for more than a few days.
- The pain intensifies or becomes unbearable.
- You notice visible damage to your teeth, like cracks, chips, or discoloration.
- Gum swelling, bleeding, or other issues accompany your sensitivity.
A dental visit can help uncover the exact cause and provide the proper treatment for long-term relief.
Professional Treatments for Sensitive Teeth
Your dentist can provide various solutions to treat tooth sensitivity and its root causes effectively. Some common treatments include:
- Fluoride application: Dentists can offer a high-concentration fluoride gel or varnish to strengthen enamel.
- Dental bonding: A resin coating can cover exposed areas of your teeth, reducing sensitivity.
- Night guards: If bruxism contributes to sensitivity, a night guard can prevent enamel wear.
- Gum grafts: A gum graft can cover exposed tooth roots in severe gum recession.
- Root canals: Decay that reaches the tooth’s nerve may require a root canal.
The Importance of Regular Check-Ups
Routine dental check-ups can help prevent tooth sensitivity—and other oral health problems. Your dentist can catch potential issues early before they lead to discomfort, and they can also provide personalized advice on tooth care that works for you.
