One of the most prevalent issues with the teeth that can affect both young and old people is tooth sensitivity. You can experience a sharp pain when taking ice cream, coffee or even cold air. This pain is usually one of the indications that the protective layers of your teeth are eroded or broken down. Learning about the causes of tooth sensitivity and the way of treating it can assist you to save your smile and avoid any further problems with teeth.

What Is Tooth Sensitivity?

Tooth hypersensitivity or tooth sensitivity is the exposure of a tooth inner layer to air or water. Tooth has small nerve endings which senses heat, cold or pressure. These nerves are activated when the protective enamel or the gum tissue is worn away (resulting in pain or discomfort).

Tooth Sensitivity Causes

1. Enamel Erosion
Your teeth are covered by the hard layer of enamel. With time it may undergo erosion because of:
• Acidic food and beverages (soda, citrus, vinegar)
• Over brushing with stiff bristles
• Teeth grinding (bruxism)
• Poor oral hygiene
With the loss of enamel, dentin is exposed – which results in sensitivity.

2. Gum Recession
The gums can also recede away because of old age or use of hard toothbrushes, or gum disease. Once gums recede, the root surface (which is not enameled) is exposed leading to pain on eating or drinking.
3. Tooth Decay or Cavities
Cavities and tooth decay leave small holes that reveal the dentin and nerves at the bottom of the tooth and leave them so sensitive particularly to sweet and cold beverages.
4. Cracked or Chipped Teeth
Even a minor crack might appear insignificant, but it can permit bacteria or thermal variations to get to the nerve of the tooth. A small head injury is enough to cause acute pain.
5. Recent Dental Procedures
It is normal to experience some sensitivity following fillings, cleanings, or whitening. This normally subsides in a couple of days but in the case where it lingers, you should seek the advice of your dentist.

How to Treat Tooth Sensitivity?

Wear Desensitizing Toothpaste
Toothpaste made specially to treat sensitive teeth prevents the transmission of the pain to the nerves. Constantly using it can help to relieve discomfort considerably. Find such ingredients as potassium nitrate or stannous fluoride.
Brush and Explore Slightly Soft Toothbrush
Enamel and gums may be damaged by brushing too hard. Apply very lightly and in a circular motion and change to a soft-bristled toothbrush to avoid additional irritation.
Shun Acidic Food and Beverages
Limit intake of soda, wine, citrus fruits and foods made of vinegar. In case you eat them, then wash your mouth with water to counter the acids.
Maintain Good Oral Hygiene
Flossing once a day, brushing twice a day will help avoid the accumulation of plaque and gum issues, which are among the greatest causes of sensitivity.
Get Professional Fluoride Fittings
Fluoride gel or varnish can be used by the dentist to enhance tooth enamel and inhibit sensitivity. Exposed root surfaces can be of particular use with this treatment.
Treat Gum Recession or Decay
In case the gum recession or tooth decay is the cause of sensitivity, professional dental care is required. Your dentist may prescribe:
• Sealing or bonding exposed dentin
• Gum grafting as a way of replacing lost gum tissue
• Root canal treatment in the severe cases

Preventing Tooth Sensitivity

• Apply fluoride toothpaste on a daily basis
• Do not brush or apply whitening pastes too frequently
• Wear a night guard in the case of teeth grinding
• See your dentist on a routine basis
• Avoid very hot or cold foods which cause pain
• These little everyday routines can help a lot in keeping your enamel and gums safe

When to See a Dentist?

When the sensitivity of the teeth does not go away in a couple of days, or it becomes more serious, it is necessary to visit a dentist. Constant sensitivity could be an indication of underlying problems like infection, advanced decay, and gum disease that could only be treated professionally.
Sensitivity in the teeth may render normal life unpleasant – but it is not something that you are bound to live with. Sensitivity can be eradicated or minimized with correct oral care routine and dental treatment in time. Covering your enamel, keeping hygiene, and checking up with your dentist are some of the major measures to ensure that your smile is strong and pain-free.
