What You Should Know About Teeth Whitening

Tooth discoloration is natural
For each and every person, teeth yellowing is a normal part of life. It simply comes with the process of aging. The inner part of the tooth, called dentin, can become discolored due to a significant events such as certain diseases, medications or injuries. The yellowing of dentin is usually due to unfortunate circumstances and not the actions of the person. The outer part of the tooth, called enamel, can also turn yellow. However, this is due to the habits or choices of the person, or just everyday life. Actions such as grinding your teeth, smoking tobacco or taking in acids from foods and drinks that you eat can thin enamel earlier, making teeth become yellow sooner.

Two types of whitening strategies
“Intrinsic” whitening refers to targeting the inner part of the tooth. The dentin soaks up whitening agent and becomes lighter. When the inner part of the tooth becomes whiter, that is reflected through the enamel. Intrinsic whitening treatments can include laser whitening, resin bonding, veneer treatment.

“Extrinsic” whitening is the removal of stains on the outer part of the tooth, the enamel. This is a much easier process and can be done at home or in-office. Techniques for extrinsic whitening can come in the several forms including trays, strips and toothpastes.

What to know before you begin
Teeth Need to be Healthy – Refrain from whitening your teeth is you already have a dental condition such as gum disease, exposed roots, cavities, crooked teeth, or gum recession. Exacerbating these problems can easily lead to further issues.

Tooth Sensitivity Can Occur – One common side effect of teeth whitening is brief sensitivity after your teeth have been exposed to whitening gel. This is normal but should still be taken into consideration. Use of a pain reliever is acceptable when sensitivity is particularly high.

It Won’t Last Forever – Tooth whitening does not last for forever. That’s the unfortunate truth. Regardless of treatments, teeth naturally yellow overtime with age, diet and lifestyle. Most results from a round of whitening last from 6 months up to 2 years, depending on the individual. Then it will be time for another round.

More is More – Exercise caution as you strive for whiter teeth. Too much whitening in too short of a time period will cause permanent damage to teeth. Whitening too frequently can cause teeth to look translucent or discolored, of which the only fix is completely replacing the affected teeth. Whitening is safe when done correctly.

When you should NOT whiten
● Your teeth are already very sensitive
● You have gum recession or sensitivity
● You have sensitivity to hydrogen peroxide
● You have cavities
● You are pregnant or breastfeeding
● You’re under age 18
● You have visible plastic fillings or crowns

Dental Erosion

brushing teethCavities aren’t the only thing that can hurt your teeth. A growing number of people these days suffer from dental erosion. Dental erosion is often caused by the acid in the food we eat and the beverages we drink. It has a chemical reaction that essentially softens the enamel, which is the protective layer over the teeth and over time, the enamel can erode. It can also lead to both tooth and gum problems.

Luckily, there are ways to prevent this from happening. Don’t brush your teeth right after eating or drinking something that would be acidic. If you drink a soda or have foods such as oranges, lemons or grapefruit, or even sour candies – rinse your mouth out with some water. Wait at least 30 minutes before brushing. Your enamel is going to be soft for a little while and you want to wait until it gets harder again before you brush.

Lastly, use a soft toothbrush and don’t overbrush. Also, stay away from overly-abrasive toothpaste.
