Whitening: 5 Things to Know About Getting a Brighter Smile

Brushing and flossing are everyday ways to keep your teeth bright, white and healthy. Still, if you might feel your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone. When the American Academy of Cosmetic Dentistry asked people what they’d most like to improve about their smile, the most common response was whiter teeth. The American Association of Orthodontists also found that nearly 90% of patients requested tooth whitening. 

 

Thinking about teeth whitening? Get the facts first. Here are five of the most commonly asked questions about the 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 (enamel).

 

Tobacco Use

Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance. 

 

Age

Below the hard, white outer shell of your teeth (enamel) is a softer area 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 be a side effect of certain 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. Look for whitening toothpastes that have earned the ADA Seal of Acceptance for stain removal (it will tell you on the package). These toothpastes have additional polishing agents that are safe for your teeth and provide stain removal effectiveness. Unlike bleaches, these types of ADA-Accepted products do not change the color of teeth because they can only remove stains on the surface.

 

In-Office Bleaching 

This procedure is called chairside bleaching and usually requires only one office visit. The dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleach is then applied to the teeth.

 

At-Home Bleaching from Your Dentist

Your dentist can provide you with a custom-made tray for at-home whitening. In this case, 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 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, discuss options with your dentist and look for one with the ADA Seal of Acceptance. That means it has been tested to be safe and effective for teeth whitening. Get a list of all ADA-Accepted at-home bleaching products.

 

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.

Tooth Pain and Sensitivity Before or After Filling Cavities

If you have cavity symptoms, you may have pain in your teeth or in your gums. Cavity pain relief depends on the extent of your tooth decay. Regardless if your cavity symptoms are mild or severe, you should visit your dentist as you may need a filling.

Tooth Fillings for Cavity Pain Relief
Dental fillings are among the most common ways to relieve cavity pain. Here’s a basic overview of cavity pain relief with a dental filling:

• Numbness: The first thing the dentist will do is numb the area of the cavity.
• Cleaning: Once the area is numb, the dentist removes the decayed part of the tooth.
• Filling: The final step in cavity pain relief—the dentist places a filling made from the material of your choice.

Causes of Tooth Pain After Fillings
Fillings are used to replace the decayed area of a tooth, reducing the pain associated with the cavity itself. But tooth pain after filling a tooth is not unusual. Some common reasons for tooth pain after a filling include:

• Tooth sensitivity: A tooth that has just had a filling placed will be more sensitive to hot foods and cold foods, air temperature, and the pressure of biting. This type of tooth pain after filling a cavity should resolve within a few weeks. If not, contact your dentist.
• Cracked or loose tooth fillings: Tooth pain after filling a cavity can occur if the filling is not fitting properly to the tooth, or if it develops cracks. If you suspect that your tooth pain is caused by a cracked or ill-fitting filling, contact your dentist.
• Allergic reaction to tooth fillings: Some people have allergic reactions to the material used for their fillings, such as silver. To help avoid tooth pain after filling a cavity, be sure to tell your dentist about any allergies when discussing your filling choices.

Tooth Filling Pain Relief
You can reduce your risk of tooth pain after filling a cavity by avoiding common sensitive teeth triggers, including very hot or cold foods. In addition, toothpaste designed for sensitive teeth can help minimize the possible sensitivity and tooth pain after filling a cavity. Crest Gum and Sensitivity oral care products are formulated to help relieve the pain associated with sensitivity fast while offering additional protection against food and drinks that cause sensitivity.

If you have cavity symptoms, you may have pain in your teeth or in your gums. Cavity pain relief depends on the extent of your tooth decay. Regardless if your cavity symptoms are mild or severe, you should visit your dentist as you may need a filling.

When you have a dental procedure, you may experience sore teeth afterward. Sore teeth are common after many dental procedures, whether it is something as simple as a cavity filling or as complicated as gum surgery.

Sore Teeth After Filling
Whether you suffer from short-term sore teeth after receiving a filling or long-term sensitive teeth, it is important to follow a complete oral care routine. The Crest Pro-Health Sensitive Shield collection of products can help keep sore teeth clean and healthy, with a toothpaste designed to protect your sensitive teeth.

• Gentle Brushing: The Oral-B Sensi-Soft Manual Toothbrush is easy on sore teeth.
• Soft Flossing: Oral-B Glide Pro-Health Comfort Plus Mint Floss is shred-resistant and extra soft.
• Sensitivity Protection: Crest Gum and Sensitivity Toothpaste starts treating sensitivity immediately at the source while helping to fight plaque, gingivitis, and cavities.

How Safe Is Tooth Whitening?

Below is an excerpt from an article found on Colgate.com 

Over a decade of research has proven bleaching and other whitening methods to be both safe and effective. Several products in the market today have shown no adverse effects on teeth or gums in substantial clinical and laboratory testing. Be sure to look for clinically proven products, follow directions and consult with your dental professional.

In the past, the higher bleach concentrations used in-office treatment resulted in more sensitivity. Today, however, bleaching gels are well buffered, making sensitivity less of an issue. Sensitivity may occur in people after whitening procedures, particularly when they eat hot or cold foods, but usually disappears after 48 hours and stops completely when treatment is stopped.

If you do experience sensitivity, there are several ways you can help eliminate it:

• If using a tray applicator, wear the tray for a shorter period
• Brush with a toothpaste made for sensitive teeth that contains potassium nitrate to help soothe tooth nerve ending
• Ask your dentist or pharmacist for a product with fluoride, which helps re-mineralize your teeth. Brush-on or wear in your trays four minutes prior to and after whitening your teeth
• Stop whitening your teeth for several days to allow you teeth to adapt to the whitening process. Within 24 hours, the sensitivity will cease. The longer you whiten your teeth, the less sensitivity you will experience

In a few cases, your dentist may discourage dental bleaching:

• If you have gum disease, teeth with worn enamel, cavities or particularly sensitive teeth
• If you're pregnant or breast-feeding
• If you have tooth-colored crowns, caps or other dental work in your front teeth, which can't be bleached

Potential Causes of Toothaches: It's Not Always a Cavity

Below is an excerpt from an article found on Colgate.com that was written by Wendy J. Woudstra

No matter how conscientious you are about your oral care routine, at some point in your life you will probably experience the discomfort of a toothache. Though a cavity is the most likely culprit, it is only one of several possible causes of toothaches.

Tooth Sensitivity
If you are experiencing sharp pains when eating or drinking hot or cold foods, it could mean you have a cavity. It may also be a sign that you may have sensitive teeth, either from receding gums or from a thinning of your tooth enamel. While you are waiting for a dental appointment to confirm the cause of your sensitive teeth, using a soft-bristled toothbrush and a toothpaste designed for sensitive teeth may help ease the symptoms.

Some Toothaches Are More Severe
If the pain you are experiencing is a sharp, stabbing pain when you bite down on your food, the cause of your toothache could be a cavity or a cracked tooth. If it's a throbbing, incessant pain, on the other hand, you may have an abscessed tooth or an infection that should be taken care of as quickly as possible.

What is Tooth Sensitivity?

What is Tooth Sensitivity?
Tooth sensitivity is a common name for dentin hypersensitivity or root sensitivity. If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful then you have sensitive teeth.

Is Tooth Sensitivity Common? 
Tooth sensitivity is very common and it has been estimated that approximately half the population experiences tooth sensitivity. Tooth sensitivity can come and go over time.

Why does Tooth Sensitivity (Dentin Hypersensitivity) Happen? 
Tooth sensitivity is usually caused by dentin on root areas exposed due to receded gums or periodontal disease. Receded gums are very common and up to four fifths of people have gum recession by the time they are 65.  

When the root of a tooth becomes exposed it does not have a layer of enamel like the crowns of your teeth. Instead the roots have a very soft covering called cementum, which once lost leaves the dentin of the root exposed.  Overzealous brushing or using a very abrasive toothpaste can also cause abrasion of the tooth's enamel surface and expose dentin. A very acidic diet - for example a diet with a lot of citrus food, pickles or sodapop - can cause tooth erosion and dissolve the tooth surface, exposing the dentin. Bulimia and GERD can also result in dental erosion and sensitivity due to acid in the mouth.

Tooth Decay and Sensitivity

What Causes Tooth Enamel Damage?
What happens when tooth enamel is damaged? The exposed part underneath becomes vulnerable to decay. Cavities aren't the only problem.

Teeth with damaged enamel can become sensitive to extreme temperatures. Suddenly, eating ice cream or sipping hot coffee can be painful or unpleasant.
