All What You Need to Know About Sensitive Teeth

Have you ever felt pain or discomfort after a bite of ice cream or a spoonful of hot soup? If so, you’re not alone. While pain caused by hot or cold foods could be a sign of a cavity, it’s also common in people who have sensitive teeth.

Tooth sensitivity, or “dentin hypersensitivity,” is exactly what it sounds like: pain or discomfort in the teeth as a response to certain stimuli, such as hot or cold temperatures.

It may be temporary or a chronic problem, and it can affect one tooth, several teeth, or all the teeth in a single individual. It can have a number of different causes, but most cases of sensitive teeth are easily treated with a change in your oral hygiene regimen.

What Are Symptoms of Sensitive Teeth?

People with sensitive teeth may experience pain or discomfort as a response to certain triggers. You may feel this pain at the roots of the affected teeth. The most common triggers include:

  • hot foods and beverages
  • cold foods and beverages
  • cold air
  • sweet foods and beverages
  • acidic foods and beverages
  • cold water, especially during routine dental cleanings
  • brushing or flossing teeth
  • alcohol-based mouth rinses

Your symptoms may come and go over time for no obvious reason. They may range from mild to intense.

What treatments can the dentist offer?

During an examination the dental team will talk to you about your symptoms. They will look at your teeth to find out what is causing the sensitivity and to find the best way of treating it. The dental team may treat the affected teeth with special ‘de-sensitising’ products to help relieve the symptoms. Fluoride gels, rinses or varnishes can be applied to sensitive teeth. These can be painted onto the teeth at regular appointments one or two weeks apart, to build up some protection. Sensitivity can take some time to settle, and you may need to have several appointments. If this still does not help, your dental team may seal or fill around the neck of the tooth, where the tooth and gum meet, to cover exposed dentine. In very serious cases it may be necessary to root-fill the tooth.

How to Whiten Sensitive Teeth?

Before you begin a whitening program, it’s important to deal with oral health problems that cause tooth sensitivity like gum disease or cavities. Thankfully, most dental health problems are treatable so you can begin a tooth whitening program once these issues have been resolved.

Visit your dentist and ask about tooth whitening for sensitive teeth. If your dentist recommends holding off whitening treatments until your other oral health issues are taken care of, be sure to follow their instructions to avoid causing any further damage to your teeth or increasing your sensitivity.

1. Professional Whitening Treatment

Professional teeth whitening done by a dentist might be the best option for those with sensitive teeth. While professional whitening is the most expensive option, it allows a dentist to monitor the process and ensure your teeth remain safe throughout. They can also use gels and desensitizers to help reduce sensitivity while they whiten your teeth. In-office whitening also typically is the most effective at removing stains and is long-lasting compared to other whitening options.

You can also look into purchasing a professional whitening kit from your dentist, which typically costs less than in-office whitening.

2. Porcelain or Composite-Resin Veneers

If your teeth are severely stained, or your dentist determines that your teeth cannot handle whitening, then veneers may be the next best option. While porcelain veneers require a healthy amount of tooth enamel to place, composite-resin veneers don’t require as much, which may be a better option for those that have sensitive teeth due to decreased enamel. Your dentist can help decide which veneers are right for you.

3. At-Home Whitening Options

At-home tooth whitening options are the most cost-effective way you can give your smile a boost. However, many of these options can easily irritate sensitive teeth and gums, especially when not used as directed.

When choosing between whitening toothpaste, gels, strips, rinses and over-the-counter whitening trays, be sure to read the labels for warnings about sensitivity. There are many whitening products that are specially formulated to work with sensitive teeth, so look for these choices when looking for an over-the-counter whitening treatment.
