Tooth sensitivity can stop you in an instant. A sip of cold water or a quick breath of winter air can send a sharp signal through your teeth. You might start to avoid certain foods. You might chew on one side. You might even delay care because you feel uneasy. A general dentist understands this pain and treats it every day. A Lower Manhattan dentist looks for simple causes first. That may include worn enamel, gum loss, tooth grinding, or a small crack. Then the dentist uses clear steps to calm the nerves and protect the tooth. You learn what is happening. You see what can help right away. You also see what can prevent severe pain later. This blog explains how a general dentist finds the cause, eases your discomfort, and helps you feel safe eating, drinking, and smiling again.
Why Your Teeth React To Hot And Cold
Your teeth should not hurt when you eat or drink. When they do, it often means the inner layer of the tooth is open. That inner layer holds tiny tubes that lead to the nerve. When cold, heat, sweet food, or touch reaches those tubes, the nerve sends a sharp signal.
Common triggers include:
- Cold drinks or ice cream
- Hot coffee or tea
- Sweet or sour food
- Brushing or flossing one sore tooth
A general dentist uses these details to narrow the cause. That first talk with you is as important as the exam.
How Dentists Find The Cause Of Sensitivity
You start with a clear story. You describe when the pain starts, how long it lasts, and what sets it off. You also share habits like grinding, clenching, or using whitening products. Then the dentist examines each tooth with care and patience.
Typical steps include:
- Looking for worn enamel and exposed root surfaces
- Checking for gum loss and deep pockets
- Testing each tooth with air or cold
- Taking X-rays when needed
The dentist rules out problems that need urgent care, such as deep decay or infection. That matters because true nerve infection causes long, throbbing pain, not just brief zaps.
Common Causes And What Your Dentist Does
Tooth sensitivity has many causes. Your dentist matches each cause with a simple first step. The goal is to protect the nerve and stop the pain.
| Cause | What You Often Feel | Common Dental Treatment |
|---|---|---|
| Worn enamel from brushing hard | Short, sharp pain with cold on one or two teeth | Soft brush, gentle method, fluoride varnish, sensitive toothpaste |
| Gum loss and exposed roots | Cold and touch pain near the gumline | Desensitizing varnish, bonding resin, gum treatment, possible graft |
| Tooth grinding or clenching | General soreness, worn edges, morning pain | Night guard, bite adjustment, repair of worn spots |
| Tooth decay or cracked tooth | Cold sensitivity that lingers, pain with chewing | Filling, crown, or root canal if the nerve is harmed |
| Whitening products | Short, sharp pain in several teeth during whitening | Pause or slow whitening, fluoride gel, custom trays |
Fluoride And Desensitizing Treatments
Many general dentists start with fluoride and desensitizing care. These treatments strengthen enamel and block the tiny tubes that reach the nerve. They do not change the shape of your tooth. They give your tooth a shield.
Common options include:
- Fluoride varnish painted on sensitive spots
- High fluoride toothpaste for home use
- Gels or rinses that numb the exposed tubes
The American Dental Association explains how fluoride protects your teeth and lowers pain from early decay. You can read more at MouthHealthy.org.

Repairing Worn Or Damaged Teeth
If the surface of a tooth is damaged, your dentist often needs to rebuild it. This step protects the nerve and restores strength. It also helps you bite and chew in a balanced way.
Possible treatments include:
- Small fillings to cover worn or decayed spots
- Bonding resin over exposed roots at the gumline
- Onlays or crowns for cracked or heavily worn teeth
Each choice depends on how serious the damage is. Your dentist usually shows you pictures or X-rays so you can see why a certain repair is needed. Clear images remove doubt and fear.
When Sensitivity Means A Deeper Problem
Brief pain that stops fast often points to exposed tubes. Yet long pain can mean the nerve is sick. You might feel throbbing at night or pain that lingers for a minute or more after a cold. You might also notice swelling or a bad taste.
In those cases, a dentist may need to:
- Remove deep decay
- Treat the nerve with a root canal
- Place a crown to seal and protect the tooth
The National Institute of Dental and Craniofacial Research explains tooth decay and nerve damage in clear terms at nidcr.nih.gov. That resource can help you understand why early care matters.
Home Habits Your Dentist Will Ask You To Change
Treatment in the chair works best when your daily habits support it. Your dentist will talk with you about three key steps at home.
First, how you brush.
- Use a soft brush
- Use small circles, not hard scrubbing
- Brush for two minutes, twice each day
Second, what you eat and drink.
- Limit soda, sports drinks, and sour candy
- Drink water after acidic food
- Do not sip sugary drinks over many hours
Third, how do you protect your teeth at night.
- Wear a night guard if you grind or clench
- Try simple stress relief, such as stretching before bed
When You Should Call A Dentist
You do not need to wait for severe pain. You should call a general dentist when:
- Sensitivity lasts more than a week
- Pain wakes you from sleep
- You avoid chewing on one side
- You see a crack, chip, or gum loss
Quick care often means simple treatment. Delay can lead to deeper nerve problems and higher costs. You deserve to drink a cold glass of water without fear. You also deserve clear answers and steady care from a dentist who respects your pain and your time.
