Teeth whitening

Teeth whitening or bleaching is a simple, non-invasive dental treatment to change the color of natural tooth enamel to enhance the beauty of your smile. Teeth whitening may be accomplished in a dental office or at home. The procedure uses a chemical called peroxide to bleach or whiten the teeth.

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.

Is whitening good for teeth?

Over 10 years of clinical use of teeth whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings. Do teeth whiteners damage a tooth’s nerve? There’s no evidence that the teeth whitening process has a harmful effect on the health of a tooth’s nerves.

Sedation Dentistry

Sedation dentistry helps you feel calm, relaxed and at ease during dental procedures. It’s a moderate level of sedation, so you’re still technically awake but feeling very carefree. It’s sometimes called conscious sedation dentistry or “twilight sleep” because it creates a state of short-term amnesia (forgetfulness) where you experience insensitivity to pain without the loss of consciousness.

What types of sedation are used in dentistry?

There are varying levels of sedation dentistry based on your unique needs. Factors include your level of anxiety, the length of your procedure, your health history and personal preferences. The most common types of sedation dentistry include nitrous oxide, oral conscious sedation and intravenous (IV) sedation.

Nitrous oxide

Nitrous oxide is commonly known as “laughing gas.” You inhale nitrous oxide through a mask or nosepiece, and calming effects begin within three to five minutes. Your dentist controls the amount of sedation you receive and adjusts dosages accordingly throughout your procedure. Once your treatment is over, your dentist gives you pure oxygen to flush the nitrous oxide out of your system. Because the laughing gas leaves your system so quickly, you’ll be able to drive yourself home after the procedure.

Oral conscious sedation

With oral conscious sedation, your dentist gives you sedative medication (usually in pill form) about an hour before your procedure begins. Most dentists use triazolam (Halcion®), which is in the diazepam (Valium®) family. But your dentist might use other medications, too, including zaleplon and lorazepam. Dentists often used liquid sedation in pediatric dentistry, such as midazolam oral syrup.

Oral sedation makes you quite groggy, and you may even fall asleep. But you’ll still be able to communicate with your dentist if necessary, and you’ll awaken with a gentle nudge. Because oral sedation temporarily affects your memory and motor skills, you’ll need a friend or family member to drive you home after your procedure.

Intravenous (IV) sedation

IV sedation dentistry is the deepest form of conscious sedation available in a dental office setting. Your healthcare provider delivers sedative medications directly to your bloodstream through an IV line. During your procedure, your dentist monitors your heart rate blood pressure and oxygen levels. They can adjust your dosage at any point and can use reversal medications if necessary. Most people who receive IV sedation dentistry fall asleep and have little to no memory of their treatment when they wake up. This option is best for people with severe dental anxiety or those who are undergoing lengthy procedures.

What happens before sedation dentistry?

You’ll talk with your dentist about sedation options during your initial consultation. They’ll discuss your health history and ask about any medications or supplements you’re taking. Once they’ve gathered all the necessary information, they’ll make sedation recommendations based on your specific needs.

In most cases, you shouldn’t eat or drink anything for at least six hours before your dental appointment. Unless otherwise noted by your dentist, you should take all routine medications without interruption.

Be sure to tell your dentist if you’re taking any blood thinners, though, such as warfarin. They may ask you to skip these medications for a few days leading up to your procedure.

What happens during sedation dentistry?

Your dentist gives you sedative medications before beginning your procedure. You’ll still receive local anesthetic to numb your teeth and gums, but your dentist usually does this once you’re already feeling comfortable from the sedatives.

What happens after sedation dentistry?

Unless you choose nitrous oxide as your sedation option, you’ll need a trusted friend or family member to drive you home after your appointment. You should go straight home and rest while the sedative medication wears off.

What are the advantages of sedation dentistry?

Sedation dentistry eases anxieties and phobias, helping you remain calm and comfortable during dental procedures. Because your dentist can often work faster when you’re under sedation, it can result in fewer appointments. Finally, many people have so much dental anxiety that they avoid going to the dentist altogether. Sedation dentistry helps you feel more comfortable so you can receive the care you need and deserve.

Recovery time

Recovery times vary. It depends on what type of sedation you choose and how your body responds to the medications. In general, people who have nitrous oxide recover within 15 to 30 minutes and can drive themselves home following their appointment. Those who choose oral conscious sedation or IV sedation typically need about 24 hours for full recovery.
