Causes of Tooth Sensitivity

Make sense of sensitivity. It's a familiar feeling when encountering certain foods and temperatures that involve pain or discomfort. Your teeth's dentine contains thousands of microscopic tubules, or channels, that lead to the pulp. When exposed to the elements, these channels allow hot, cold, acidic or even sticky substances to reach the nerves, causing pain.
Some factors that contribute to sensitive teeth may include:
All teeth whitening
It's common for some people to feel sensitivity a few hours after any whitening treatment—that's just the whitening agent finally reaching nerves in the pulp. It's completely harmless and shortly goes away.
Hard impact
This includes biting on hard candy and ice, or grinding your teeth. Cracks expose the nerve endings in tooth pulp, which cause discomfort when they come into contact with your opposing teeth, food and bacteria.
Receding gums
Unfortunately this happens naturally with age—gums recede and expose the previously protected dentine.
Brushing too hard
The easiest way to damage your enamel is with harsh bristles that cause abrasion. Try to brush gently in a circular motion.
Acidic foods and mouthwash
The acidity burns down enamel, and mouthwashes can further enrage sensitivity.
Too much soda
The sugary by-products will degrade enamel by softening it, leaving it vulnerable. Low-sugar soda helps but is still very acidic.

Treatment For Tooth Sensitivity

Effective and efficient. Research and consumer feedback indicate desensitising gel is the most effective treatment for sensitive teeth. In the process, teeth are also strengthened and increase resistance to acidic foods and bacteria. Together with the Smileflex desensitising gel, any of the following are recommended:
Use sensitive toothpaste
This type of toothpaste has ingredients specifically designed to fill the exposed tubules in the dentine.
Brush softer
Use a soft-bristled toothbrush at least twice a day and replace every 3 months.
Clean teeth after eating
It is important to remove bacteria that might otherwise settle and corrode enamel. Cleaning your teeth might include gentle brushing, flossing or simply swishing water around for a few seconds.
Avoid clamping
Eat less hard foods and avoid grinding your teeth. Many people grind unconsciously when they're sleeping and the best treatment for the pain is a Smileflex night guard.

Frequently Asked Questions

You asked, we answered! We’ve put together some of the most commonly asked questions about our custom teeth whitening kits. If you can't find the answers you're looking for below, head over to the Smileflex Help Centre for even more information.

When you visit a dentist for a custom teeth whitening kit, the teeth impressions taken are sent to a dental laboratory like us anyway! Our Smileflex dental technicians create your custom whitening trays the same as they would for a dentist. We also use the same active ingredients in our whitening gel that dentists use.

Yes but keep in mind, artificial dental work will not whiten. They are colour matched at the time they are created and do not have pores. The colour of your dental work cannot be changed (unless it is replaced).

All teeth whitening work by absorbing into pores on the tooth surface. The active whitening agent in our dental grade formula is Hydrogen Peroxide (H2O2), a naturally occurring compound which breaks down readily into water (H2O) and a single oxygen molecule (O). This single oxygen molecule is a strong oxidising and disinfecting agent, and is what gives Hydrogen Peroxide such effective whitening properties.

Teeth whitening is only achieved with either Hydrogen Peroxide (HP) or Carbamide Peroxide (CP) and requires custom-fitted trays to use. HP and CP produce the same results, however HP whitens 3x faster and requires 3x less strength to that of CP to achieve the same results. This is because of the time needed for the CP to break down into HP first.

While formulas found in LED whitening kits such as PAP and PAP+, are merely a temporary teeth "lightening" effect by dehydrating teeth rather than whitening and removing tooth stains. In the dental industry we call this "rebound" and people using those products find once their dehydrated teeth return to health 3–4 weeks later, their original tooth stains reappear (as they were never removed).

With all factors considered, it's why Smileflex chooses Hydrogen Peroxide as its active whitening agent to achieve the best and longest lasting professional results.

Yes! Our product has proven to be highly effective at removing stains from teeth including coffee, tea, wine, tobacco, tetracycline, and various other tooth stains.

Our desensitising gel is formulated to treat tooth sensitivity caused by whitening and prevents re-staining in the process. It can also be used for people with general tooth sensitivity as it rejuvenates, strengthens and desensitises enamel after treatment.
