You take a sip of iced coffee or bite into something sweet, and a sharp jolt shoots through your tooth. If that sounds familiar, you are far from alone. Tooth sensitivity is one of the most common complaints we hear, and the good news is that it is almost always treatable once you understand what is behind it. If you have been searching for answers about tooth sensitivity in North Andover, Dr. Gary C. Demetriou can help you pinpoint the cause and find real, lasting relief rather than just working around the discomfort.
What causes that sharp twinge
Sensitivity happens when the protective outer layer of your tooth, the enamel, wears thin or the gum pulls back to expose the softer layer underneath. That layer, called dentin, contains tiny channels that lead straight to the nerve. When dentin is exposed, hot, cold, sweet, or acidic triggers can reach the nerve and cause that familiar wince.
Several everyday things can lead to this exposure, and often more than one is at play:
- Brushing too hard or using a stiff bristled toothbrush, which wears away enamel and irritates the gums
- Acidic foods and drinks like citrus, soda, and wine that gradually erode enamel over time
- Gum recession that exposes the sensitive root surface of the tooth
- Teeth grinding, which wears down enamel and can create small cracks
- A cracked or chipped tooth, or a worn filling that no longer seals properly
- Tooth decay or gum disease that has reached a point where it affects the nerve
Because the causes vary so much, the fix that works for one person may not be right for another. That is exactly why a proper exam matters before you settle on a solution.
It also helps to know that sensitivity is not always permanent. In many cases it comes and goes depending on the season, your habits, or a temporary irritation, and it can improve significantly once the underlying trigger is addressed. The key is figuring out whether your sensitivity is a passing annoyance or a signal that something in the tooth or gum needs attention. That distinction is difficult to make on your own, but it is quick and painless to sort out in the chair.
When sensitivity is worth a closer look
Occasional, mild sensitivity is common and often manageable. But sensitivity can also be an early warning that something needs attention. It is worth booking a visit if you notice any of the following.
- Sensitivity that is getting worse or lasting longer than a few seconds
- Pain in a single specific tooth rather than a general sensitivity across many teeth
- Discomfort that lingers well after the hot or cold trigger is gone
- Sensitivity paired with visible pitting, a dark spot, or a chip in the tooth
- Tenderness along the gumline or gums that bleed when you brush
These signs can point to a cavity, a cracked tooth, or gum disease, all of which are far easier to treat early. Catching a problem at the sensitivity stage often means a simpler, gentler fix than waiting until it becomes painful.
How your North Andover dentist treats it
The right treatment depends entirely on the cause, which is why Dr. Demetriou starts with a careful exam to find the source rather than just masking the symptom. Once the cause is clear, the solution is usually straightforward. Common approaches include:
- Desensitizing toothpaste or a professional fluoride treatment to strengthen enamel and calm the nerve response
- A filling or bonding to repair a cavity, worn area, or exposed root surface
- Treating gum disease or addressing recession so the root is no longer exposed
- A dental crown when a tooth is cracked or significantly worn
- A custom night guard if grinding is wearing down your enamel while you sleep
Often the answer is simpler than patients expect. Something as minor as switching to a soft bristled brush and easing up on pressure can make a real difference, and Dr. Demetriou will always start with the least invasive option that solves the problem.
Simple habits that help at home
Alongside professional care, a few small changes protect your enamel and reduce day to day sensitivity. These are easy to fold into your routine.
- Brush gently with a soft bristled toothbrush and a fluoride toothpaste made for sensitive teeth
- Wait about thirty minutes after acidic food or drink before brushing, so you do not scrub softened enamel
- Use a straw for acidic or cold beverages to limit direct contact with your teeth
- Keep up with regular cleanings and checkups so small issues are caught early
The American Dental Association also notes that sensitive teeth can be a sign of an underlying issue, so persistent sensitivity is always worth mentioning to your dentist rather than simply tolerating.
You do not have to live with sensitive teeth
Too many people quietly adjust their lives around sensitive teeth, skipping the ice water, chewing on one side, or bracing for that jolt with every cold sip. You do not have to. In most cases, sensitivity has a clear cause and a clear solution, and relief is more achievable than you might think.

One longtime patient, Paige M., shared that it is “a very efficient friendly office” where “the staff, especially the hygienists are wonderful.” If sensitive teeth have been bothering you, that is exactly the kind of environment where you can get answers without pressure.
