Why Are My Teeth Sensitive All of a Sudden?

One minute you are drinking your cold water. The next minute a sharp little sting shoots through your tooth. It catches you off guard.

Sudden tooth sensitivity usually means something has changed around the tooth. Sometimes it is temporary. Times it points to a problem that needs a dentist’s attention especially if the pain keeps coming back or starts happening without food or drink.

What Can Suddenly Make Your Teeth Sensitive?

Your teeth have an outer layer called enamel. Beneath that layer sits dentine, which’s much more sensitive because it contains tiny channels that lead to the nerve. When enamel wears down or when your gums pull back those channels become easier for hot, cold, sweet or acidic substances to reach.

Brushing hard is one common culprit. Using an abrasive whitening toothpaste for a long time is another. If you recently had teeth whitening, a few days of sensitivity is not unusual.

Changes You Might Have Missed

Sometimes the trigger is something you have started doing without really thinking about it. Maybe you have begun drinking fizzy drinks. Perhaps you have been squeezing lemon into your water each afternoon. Acid gradually softens enamel, which leaves the layer underneath more exposed.

Grinding your teeth can also wear away enamel. You might not even know you are doing it because it often happens while you are asleep.

A cracked tooth is another possibility. That deserves attention because sensitivity from a crack can feel very specific especially when you bite down or release your bite.

Could It Be A Cavity?

Yes. A new cavity can cause sensitivity especially once decay goes deeper into the tooth. However sensitivity does not automatically mean you have a cavity.

• Cold drinks suddenly becoming uncomfortable even though they never bothered you before.

• Sweet foods setting off a twinge then everything feels normal again.

• Pain that lingers after the trigger is gone. That one is worth taking

• One particular tooth reacting while the teeth around it feel completely fine.

What Can You Do Right Now?

Start by being gentler with your teeth. Use a bristled toothbrush and do not scrub as though you are trying to remove a stain from a kitchen counter. You are not.

A toothpaste made for teeth can also help. Give it some time than expecting the first brushing to fix everything. Cutting back on drinks is sensible especially if you sip them slowly throughout the day.

When A Dentist Should Take A Look

A dentist can check for decay enamel wear, gum recession or a crack. The cause matters because treating sensitivity without dealing with what’s underneath is like turning down an alarm while leaving the problem alone.

Get checked sooner if the pain is severe lasts after hot or cold foods are gone happens without a trigger or comes with swelling. Do not keep testing the tooth with ice water just to see if it is still there. Honestly teeth are not great at giving clues that way.

So Why Did It Happen So Suddenly?

Sometimes the damage was not sudden all. You simply noticed the sensitivity enough enamel had worn away or enough gum had receded to expose dentine.

Sometimes there really is a new problem, such, as decay or a cracked tooth. That is why a sudden change deserves an attention instead of being brushed off.
