why are my teeth sensitive all of a sudden

Exercise Daily – Are you wondering why are my teeth sensitive all of a sudden? Do you find yourself unable to enjoy a hot cup of coffee or a cold glass of water because of tooth pain? Do you avoid sweets and acidic meals because they bring you dental discomfort? 

You should seek medical attention if you suddenly get twinges or shock-like discomfort in your teeth.

Dental sensitivity is a temporary feeling induced by a stimulus such as heat or cold being applied to the dentin. Dentin is the layer of tissue underlying the hard, white enamel of the teeth. 

When the protective layer of the dentin is lost, the nerves inside the teeth are left without a buffer. Keep in mind that although some degree of oral sensitivity is considered normal, discomfort associated with common activities might indicate the presence of more serious dental problems.

Causes of Sudden Teeth Sensitivity

Dental sensitivity may affect persons of any age. However, it’s more likely in women and young adults between the ages of 18 and 44 who have receding gums. The loss of the protective covering over the dentin is the most common cause of tooth sensitivity.

In order to determine the source of your tooth sensitivity, your dentist will likely do an oral examination. So, if you wonder why are my teeth sensitive all of a sudden, visit your dentist. He might ask you specific questions about when you get these flashes of pain. 

The following are some of the most significant perpetrators to be aware of:


Eating acidic or hard foods might be detrimental to your dental health. Beverages such as juices, citrus fruits, and sports drinks might aggravate dental sensitivity.


Chewing on ice is a practice that should be avoided since it may shatter the enamel of your teeth or grind it down over time.

Using a Hard Bristle Brush

Every abrasive procedure has the potential to enhance tooth sensitivity. According to the American Dental Association, habits such as using a hard-bristled toothbrush and cleaning your teeth violently might cause dental sensitivity.

Teeth Whitening

Teeth whitening is a procedure in which the teeth are bleached. Sensitivity may occur as a transient side effect of a whitening procedure. However, it can also occur as a consequence of using too strong whitening solutions or whitening teeth too regularly. 

Following the manufacturer’s recommendations on any whitening product, as well as working with your dentist, may help.

Tooth Decay

Tooth decay is a term used to describe the deterioration of teeth. It just takes a little cavity to eat away enough dental enamel to expose dentin and create pain. So, if you ask your doctor why are my teeth sensitive all of a sudden, he might suggest a filling or a crown.

Gum Related Sensitivity

Gum-related tooth sensitivity may be caused by a variety of factors, including brush abrasion, pocket reduction surgery, crown preparation, excessive flossing, and gum disease. Gums also retreat as we get older, which might enhance sensitivity even more.

Split Teeth

If you feel sensation when you bite down, it might be an indication of a broken tooth. It is necessary to seek emergency medical assistance. Following a dental operation, you may suffer transient sensitivity to the teeth and gums. However, this should subside after four weeks.

Digestive Disorders

Frequent vomiting associated with bulimia causes stomach acids to erode away at the surface of the teeth. Acid reflux might have the same impact on the health of your teeth.

Sinus Infections

A sinus infection may cause your teeth to suffer because of pressure and inflammation. If your teeth and head hurt more when you bend over with your head down, you may have a sinus infection.


Although pregnancy does not directly cause tooth sensitivity, the hormonal changes that occur throughout the process might influence your gums. This might cause discomfort or pain.

Weather Changes

Cold air passing over your teeth might cause an unpleasant twinge. You might not realize why are my teeth sensitive all of a sudden, but your dentist will. He may perform a sensitivity test on you by blowing air over your teeth.


In the event that stress drives you to grind your teeth, this might result in tooth damage. This may even lead to dental sensitivity. Because this grinding, which is referred to as bruxism, often happens when you are sleeping, you may be completely unaware that you are doing it. 

Grinding may cause a variety of issues, from tooth destruction to migraines and hearing difficulties.
