Brushing and flossing are everyday ways to keep your teeth bright, white and healthy. Still, if you might feel like your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone. When a study was done asking people what they’d most like to improve about their smile, the most common response was whiter teeth.
Thinking about teeth whitening? Get the facts first. Here are five of the most commonly asked questions about the treatment process.
Why Did My Teeth Change Color?
Over time, your teeth can go from white to not-so-bright for a number of reasons:
Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth also known as enamel.
Tobacco Use
Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it is mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.
Age
Below the hard, white outer shell of your teeth called enamel, is a softer layer called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through.
Trauma
If you’ve been hit in the mouth, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
Medications
Tooth darkening can also be a side effect of certain medications such as antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
How Does Teeth Whitening Work?
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Does Whitening Work on All Teeth?
No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on caps, veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.
What Are My Whitening Options?
Talk to your dentist before starting. If you are a candidate, there are four ways to put the shine back in your smile:
Stain Removal Toothpastes
All toothpastes help remove surface stain through the action of mild abrasives that scrub the teeth. These toothpastes have additional polishing agents that are safe for your teeth and provide stain removal effectiveness. Unlike bleaches, these types of products do not change the color of teeth because they can only remove stains on the surface.Also, in case of these external stains- those caused by excessive drinking of tea, coffee or those stains produced by chromogenic bacteria- can be removed through ultrasonic scaling which is a professional cleaning of your teeth. This is carried out by the dentist, after which if still the stains persist, bleaching treatment can then carried out.
In-Office Bleaching
This procedure is called chair side bleaching and usually the first step would be to apply either a protective gel to your gums or a rubber shield to protect your gums from the bleaching agent. Bleach is then applied to the teeth in order to obtain a whiter shade of your teeth. This procedure may include two or more appointments depending on how white you want your teeth to be.
At-Home Bleaching from Your Dentist
Your dentist can also provide you with a custom-made tray for at-home whitening. In such a treatment procedure, the dentist will give you instructions on how to place the bleaching solution in the tray and for what length of time. This may be a preferred option if you feel more comfortable whitening in your own home at a slower pace, but still with the guidance of a dentist. Out-of-office i.e. at-home bleaching can take anywhere from a few days to a few weeks.
Over-the-Counter Bleaching Products
You may see different options online or in your local grocery store, such as toothpastes or strips that whiten by bleaching your teeth. The concentration of the bleaching agent in these products is lower than what your dentist would use in the office. If you are thinking about using an over-the-counter bleaching kit,do make sure to discuss the options with your dentist and look for one which has an approved safety seal. This means that the product has been tested to be safe and is effective for teeth whitening.
Are There Any Side Effects from Teeth Whitening?
Some people who use teeth whiteners may experience tooth sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.
Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and talk to your dentist before purchasing any over-the-counter tooth whitening products.
To conclude, teeth whitening is a treatment procedure which requires appropriate consultation with your dentist so that we can formulate a treatment plan designed to overall give you a bright natural smile without compromising on aesthetics and at the same time without damaging your teeth.
