Tooth sensitivity is a common dental issue that can make everyday activities like eating, drinking, and brushing uncomfortable. Whether it’s triggered by hot or cold foods, sugary substances, or even a breath of cold air, the discomfort caused by sensitive teeth can be frustrating. Fortunately, there are effective solutions to manage and alleviate this condition, and with the right treatment, you can get back to enjoying your favorite foods without worry.
At Roseborough Dental in Mississauga, we understand how disruptive tooth sensitivity can be. In this blog, we’ll dive into the common causes of tooth sensitivity, what you can do to manage it, and the dentist-recommended treatments that can help restore comfort to your smile.
What Is Tooth Sensitivity?
Tooth sensitivity, also known as dentin hypersensitivity, occurs when the underlying layer of your teeth, called dentin, becomes exposed. Dentin contains tiny tubules that lead directly to the nerves in your teeth. When this layer is exposed, it can cause pain or discomfort when your teeth come into contact with certain triggers, such as hot, cold, sweet, or acidic foods and drinks.
Tooth sensitivity is a common issue and can range from mild to severe. For some, it’s a temporary inconvenience, while for others, it can be an ongoing problem that requires treatment.
Common Causes of Tooth Sensitivity
Tooth sensitivity can arise from various factors, many of which are linked to habits or conditions that affect the enamel and gums. Here are some of the most common causes:
1. Worn Tooth Enamel
Enamel is the protective outer layer of your teeth. Over time, it can wear down due to factors like poor oral hygiene, acidic foods and drinks, and abrasive brushing. Once enamel wears away, the dentin beneath is exposed, leading to increased sensitivity.
- Cause: Brushing too hard, eating acidic foods (like citrus fruits or soda), or using abrasive toothpaste can gradually wear away enamel.
2. Gum Recession
Your gums naturally recede as you age or as a result of gum disease, brushing too aggressively, or using a hard-bristled toothbrush. When gums recede, the roots of your teeth, which are more sensitive than the crown, become exposed, leading to discomfort.
- Cause: Gum disease, poor brushing techniques, and even genetics can contribute to gum recession.
3. Tooth Grinding (Bruxism)
Grinding your teeth, often unconsciously during sleep, can wear down enamel and expose the dentin. This habit can also cause fractures or chips in the teeth, which can lead to increased sensitivity.
- Cause: Stress, misalignment, or even certain medications can lead to bruxism (teeth grinding).
4. Cavities or Tooth Decay
Cavities or untreated decay can lead to tooth sensitivity, especially if the decay has reached the dentin layer. The exposed dentin allows stimuli to reach the nerves, resulting in pain or discomfort.
- Cause: Poor diet, improper oral hygiene, and not seeking treatment for early cavities can all contribute to tooth decay.
5. Dental Procedures
Certain dental procedures, such as teeth whitening, fillings, or root canals, can temporarily increase tooth sensitivity. This is often a short-term issue and should subside after a few days or weeks.
- Cause: Sensitivity is a common side effect of procedures like teeth whitening or fillings, as they can temporarily irritate the tooth pulp or nerves.
6. Cracked or Fractured Teeth
A cracked or fractured tooth can expose the dentin and lead to tooth sensitivity. Fractures can also make your tooth more vulnerable to infection, which can exacerbate discomfort.
- Cause: Accidental trauma, biting hard foods, or chewing on ice can cause cracks or fractures in your teeth.
Dentist-Recommended Solutions for Managing Tooth Sensitivity
If you’re dealing with tooth sensitivity, there are a variety of treatments and strategies that can help manage the condition and restore comfort. Here are some dentist-recommended solutions:
1. Desensitizing Toothpaste
Specially formulated desensitizing toothpaste contains compounds that help block the transmission of pain signals from the tooth surface to the nerves. These toothpastes often contain potassium nitrate or strontium chloride, which help reduce sensitivity over time.
- Recommendation: Use desensitizing toothpaste twice a day for a few weeks to see improvement. Make sure to use a soft-bristled toothbrush to avoid further irritation.
2. Fluoride Treatments
Fluoride is a mineral that helps remineralize weakened tooth enamel and reduce sensitivity. Your dentist can apply fluoride gel or varnish directly to your teeth during a routine visit. You may also be given a fluoride rinse or gel to use at home.
- Recommendation: Fluoride treatments can be especially beneficial for patients with enamel erosion or those who are at a higher risk of tooth decay.
3. Dental Sealants
Dental sealants are thin coatings applied to the chewing surfaces of the back teeth (molars) to protect them from decay and reduce sensitivity. Sealants act as a barrier against bacteria and help protect the enamel from further wear.
- Recommendation: If you have deep grooves in your back teeth that are prone to decay, dental sealants may be a good preventive measure to reduce sensitivity.
4. Gum Grafting
If your sensitivity is caused by gum recession, your dentist may recommend a gum graft to cover the exposed tooth roots. This procedure involves taking tissue from another area of your mouth or using synthetic grafts to restore gum tissue.
- Recommendation: Gum grafts are effective for patients with severe gum recession and can reduce sensitivity while improving the appearance of your smile.
5. Mouthguards for Teeth Grinding
If you grind your teeth at night (bruxism), a custom mouthguard can help protect your teeth from wear and reduce sensitivity. A mouthguard will prevent your teeth from grinding against each other, reducing enamel wear and tooth damage.
- Recommendation: Your dentist can fit you for a custom nightguard to protect your teeth while you sleep.
6. Dental Bonding or Veneers
For teeth that are severely worn, cracked, or exposed due to enamel loss, dental bonding or veneers may be recommended. Bonding involves applying a tooth-colored resin to fill in chips or cracks, while veneers are thin shells placed over the teeth to restore both function and appearance.
- Recommendation: If tooth decay or cracks are contributing to your sensitivity, your dentist may recommend bonding or veneers to seal exposed dentin and prevent further discomfort.
7. Root Canal Therapy
If the sensitivity is severe and associated with a deep cavity or infection that has reached the tooth pulp, a root canal may be necessary. During this procedure, the dentist removes the infected tissue from inside the tooth and seals it, eliminating the source of sensitivity.
- Recommendation: Root canal therapy is typically reserved for more advanced cases of tooth sensitivity caused by infection or deep decay.

FAQs About Tooth Sensitivity
Can tooth sensitivity go away on its own?
In some cases, tooth sensitivity may resolve on its own, especially if it’s caused by temporary factors like teeth whitening or a recent dental procedure. However, persistent sensitivity usually requires treatment from your dentist.
How long will it take to see improvement from desensitizing toothpaste?
It typically takes about 2–4 weeks of regular use to notice a reduction in tooth sensitivity with desensitizing toothpaste.
Is tooth sensitivity a sign of serious dental problems?
Tooth sensitivity can be a sign of underlying issues, such as cavities, gum disease, or enamel erosion. If sensitivity persists or worsens, it’s important to visit your dentist for an evaluation.
Can tooth sensitivity return after treatment?
In some cases, tooth sensitivity may return if the underlying cause, such as gum recession or enamel erosion, worsens. Regular dental check-ups are important to monitor your oral health and prevent future sensitivity.
