Tooth sensitivity can make simple things like drinking cold water or brushing your teeth uncomfortable or even painful. If you live in Irvine and have noticed sharp twinges when you eat or drink, you're not alone, and there are effective ways to manage it.
Quick answer
Tooth sensitivity is a short, sharp pain when a tooth meets something cold, hot, sweet, or acidic. It usually happens when dentin, the softer layer under enamel, is exposed by enamel erosion, gum recession, decay or cracks, teeth grinding, or recent dental work. A soft-bristled brush and a toothpaste for sensitive teeth often help within a few weeks. See a dentist if sensitivity lasts more than a few weeks, gets worse, or affects only one tooth.
What tooth sensitivity feels like
Sensitivity is usually a short, sharp pain when a tooth meets something cold, hot, sweet, or acidic, or when you breathe in cold air or brush. It happens when the softer layer under your enamel, called dentin, is exposed. Dentin has tiny channels that lead toward the nerve, so temperature and pressure reach it more easily.
Common causes of tooth sensitivity
Enamel erosion. Acidic foods and drinks, or brushing too hard, can wear down enamel and expose the dentin underneath.
Gum recession. When gums pull back, the roots are exposed. Roots aren't covered by enamel, so they're more sensitive. Learn about the causes and treatment of receding gums.
Tooth decay. Cavities and cracks can expose the inner layers of the tooth.
Teeth grinding. Clenching or grinding, often at night, can wear teeth down. A night guard can help protect them.
Recent dental work. Fillings, crowns, and whitening can cause temporary sensitivity that usually fades.
What you can do at home
Use a soft-bristled toothbrush and brush gently to protect enamel and gums.
Switch to a toothpaste for sensitive teeth. It can take a few weeks of regular use to notice a difference.
Limit acidic foods and drinks like citrus, soda, and wine, and rinse with water afterward.
Keep up with brushing and flossing to prevent gum disease and decay.
See your dentist regularly so problems are found early.
How your dentist can treat sensitivity
If home care isn't enough, your dentist will look for the cause first, then recommend treatment. Options may include:
Fluoride varnish or desensitizing treatments applied in the office to strengthen enamel and calm sensitive spots
Bonding or tooth-colored fillings to cover exposed root surfaces or repair worn areas
Fillings or crowns when decay or a crack is the cause
Gum grafting for advanced gum recession
Root canal treatment if the nerve inside the tooth is damaged and other treatments don't help
Sensitivity after teeth whitening
Whitening can make teeth sensitive for a short time. It usually fades within a few days. If you're planning to whiten, ask us which option fits sensitive teeth best. Read in-office vs. take-home whitening or see our teeth whitening page.
When to see a dentist
Book a visit if sensitivity lasts more than a few weeks, gets worse, or is limited to one tooth. Call us sooner if the pain lingers long after the cold or hot is gone, if a tooth hurts on its own, or if you notice swelling. Those can be signs of a deeper problem. For urgent pain, see our emergency dental care.
Questions about tooth sensitivity
Is tooth sensitivity serious?
Often it isn't, but it can be an early sign of decay, a crack, or gum recession. An exam is the best way to know the cause.
Can sensitive teeth go away on their own?
Sensitivity from recent dental work or whitening usually fades. Sensitivity from worn enamel or receding gums often needs a change in habits or treatment.
Does sensitive toothpaste really work?
For many people, yes, especially with daily use over several weeks. If it doesn't help, let your dentist check for another cause.
