Does Tooth Sensitivity Mean A Cavity is Present?
Posted on June 6th, 2023
Many people experience mild tooth sensitivity on occasion. It’s often triggered when we consume cold foods and beverages, like ice cream or a cold drink. It doesn’t always mean you have a cavity, or that anything is wrong with your teeth. However, chronic tooth sensitivity or pain is not normal.
It’s important to be able to distinguish the difference between normal sensitivity and a dental health issue that requires treatment. Continue reading to learn more about the causes of tooth sensitivity.
What Causes Tooth Sensitivity
Many people know what triggers their tooth sensitivity, but not everyone knows what causes the discomfort to begin with. Tooth sensitivity can be caused by any of the following conditions:
- Tooth Enamel Erosion (may be caused by diet, teeth whitening treatments, age, etc.)
- Worn Tooth Fillings, Crowns, or Other Dental Restorations
- TMJ Disorders
- Bruxism (teeth grinding)
- Gum Recession
- Gum Disease
- Exposed Tooth Roots (may be caused by gum disease, harsh brushing, etc.)
- Cavities (tooth decay)
- Damaged Teeth (i.e. a cracked or chipped tooth)
The issues listed above may cause everything from mild sensitivity to pain. If at any time you are experiencing severe tooth pain you should schedule an appointment with your dentist as soon as possible.
When Does Sensitive Teeth Mean Cavities are Present?
Tooth sensitivity doesn’t always mean something is horribly wrong with your teeth. However, sometimes it can be a good indicator you have a cavity that requires professional treatment. You might need a cavity filling if:
- You notice your tooth sensitivity increases over time
- Sensitivity is present in only one tooth
- Sensitivity occurs when biting down
- Sensitivity or pain occurs spontaneously
- You notice holes, pits, or stains on the affected tooth
- Sensitivity occurs when drinking or eating hot, cold, acidic, or sugary foods
- Sensitivity doesn’t stop after you’re done eating or drinking
- You experience severe pain at times, not just mild tooth sensitivity
The main difference between cavity pain and sensitivity is the cause behind the discomfort. General tooth sensitivity is a result of thinning tooth enamel. Cavity pain is caused by exposed decay, or tooth damage, triggering nerves to respond to stimuli.
A cavity occurs when enamel has been worn away and bacteria causes the tooth to deteriorate. Cavity pain becomes more intense the larger the cavity grows. Without proper treatment, the innermost layer of a tooth will eventually become inflamed or infected and a root canal will become necessary.
Why is My Tooth Sensitive to Hot and Cold?
Have you ever wondered, Why is my tooth sensitive to cold? Or perhaps you’ve asked yourself, Why do my teeth hurt when I drink hot coffee? The answer could be dentin hypersensitivity.
The tooth is composed of multiple layers. When the topmost layer, tooth enamel, is worn down, dentin is exposed. Dentin is connected to the pulp of the tooth which contains the nerves. Therefore, when dentin makes contact with heat, cold, acid, sugar, or excess pressure, it causes those nerves to respond, resulting in sensitivity.
Does Tooth Sensitivity Go Away?
Tooth sensitivity can slowly fade over time, especially if the sensitivity is caused by a recent dental restoration, poor diet, teeth whitening, or other external cause. However, sometimes mild tooth sensitivity remains a constant in people’s lives.
Fortunately, there are ways to decrease sensitivity. Some of these methods include:
- Using a toothpaste for sensitive teeth
- Avoiding sugary and acidic foods that harm enamel
- Brushing your teeth gently
- Using a soft-bristled toothbrush
- Avoiding teeth whitening treatments
- Wearing a mouthguard at night (for individuals with TMJ or Bruxism)
- Maintaining good dental hygiene
- Gum grafting (for receding gums)
- Dental sealants
