Teeth Whitening Treatments & Procedures

There are three general approaches: Whitening toothpastes (dentifrices) At-home bleaching Over-the-counter whitening strips Over-the-counter whitening gels Over-the-counter tray-based bleaching systems (purchased at your local drug store, over the internet, by mail) Dentist supervised tray-based whitening system (whitening supplies are purchased through your dentist’s office)

In-office bleaching – also called chairside bleaching or power bleaching

How do whitening toothpastes work and how effective are they at whitening teeth?

All toothpastes help remove surface stains through the action of mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal effectiveness. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening productscontain hydrogen peroxide (a bleaching substance) that helps remove stains on the tooth surface as well as stains deep in the tooth. None of the home use whitening toothpastes can come even close to producing the bleaching effect you get from your dentist’s office. Whitening toothpastes can lighten your tooth’s color by about one shade. In contrast, light-activated whitening conducted in your dentist’s office can make your teeth three to eight shades lighter.

What about whitening strips and whitening gels? What’s the opinion on these products?
Whitening gels


These clear, peroxide-based whitening gels are applied with a small brush directly to the surface of your teeth. Instructions generally call for twice a day application for 14 days. Initial results are seen in a few days and final results are sustained for about 4 months. The retail cost for this product is about $15 for a 14-day treatment.

Whitening strips


These are very thin, virtually invisible strips that are coated with a peroxide-based whitening gel. The strips are applied twice daily for 30 minutes for 14 days. Initial results are seen ina few days and final results are sustained for about 4 months. The retail cost for this product ranges from $10 to $55 for a 14-day treatment.

Both of these products contain peroxide in a concentration that is much lower than the peroxide-based products that are used in your dentist’s office. Although some teeth lightening will be achieved, the degree of whitening is much lower than results achieved with in-office or dentist-supervised whitening systems. Additionally, use of over-the-counter products do not benefit from the close supervision of your dentist — to determine what whitening process may be best for you, to check on the progress of the teeth whitening process and look for signs of gum irritation. On the positive, the over-the-counter gels and strips are considerably less expense (ranging from $10 to about $55) than the top-of-the line in-office whitening procedures, which can cost nearly $800.

Generally, what’s involved in the typical tray-based, tooth whitening procedure?

For the more traditional types of teeth whitening procedures using tray-based tooth whitening systems purchased over-the-counter or through your dentist’s office, the first step involves filling a mouth guard-like tray with a gel-like whitening solution — which contains a peroxide-bleaching agent. This tray is then placed over the teeth and worn for a period of time, generally from a couple hours a day or every day during the overnight for up to 4 weeks and even longer (depending on the degree of staining and desired level of whitening). (For more information, see section about mouthpiece trays below.)

Generally, what’s involved with an in-office-based tooth whitening procedure?

Bleaching procedures performed in the dentist’s office involve a few different or additional steps — namely, that a protective gel or guard is positioned over the gums before the bleaching agent is applied, the bleaching agent is applied directly to the teeth, and the whitening process is hastened with the use of heat, a special light, or laser light that is directed at the chemically coated teeth. There are other differences that are addressed in the next question.

What are the main differences between in-office bleaching procedures and the at-home and over-the-counter tray-based bleaching systems? Strength of bleaching agent

For starters, over-the-counter home use products and dentist-supervised at-home products usually contain a lower strength-bleaching agent (from 10% carbamide peroxide–which is equivalent to about 3 percent hydrogen peroxide — up to 22% carbamide peroxide). In-office, professionally applied teeth whitening procedures products contain hydrogen peroxide in concentrations ranging from 15 to 43 percent.

Mouthpiece trays


With dentist-supervised at-home bleaching products, your dentist will take an impression of your teeth and make a mouthpiece tray that is customized to exactly fit your teeth. This customization allows for maximum contact between the whitening gel, which is applied to the mouthpiece tray, and the teeth. A custom-made tray also minimizing the gel’s contact with gum tissue. Over-the-counter whitening products do contain a mouthpiece tray, but the “one-size-fits-all” approach means that the fit will not be exact. Ill-fitting trays can irritate the gum and soft tissue by allowing more bleaching gel to seep onto these tissues. With in-office procedures, the bleaching agent is applied directly to the teeth.

Additional protective measures

In the office setting, your dentist will apply either a gel to the gum tissue or use a rubber shield (which slides over the teeth) prior to treatment to protect your gums and oral cavity from the effects of the bleaching. Over-the-counter products don’t provide these extra protective measures.

Speed of the bleaching process

Dentist-supervised at-home bleaching and over-the-counter bleaching products typically need to be applied every day for 1 or 2 hours or every overnight for up to 4 weeks. In-office bleaching provides the quickest and most effective way to whiten teeth. With in-office bleaching, the whitening product is applied directly to the teeth. These products can be used in combination with heat, a special light, and/or a laser. The light and/or heat accelerate the whitening process. Results are seen in only 1, 30- to 60-minute treatment. To achieve dramatic results, however, several appointments are usually needed. With laser-enhanced bleaching, however, dramatic results can be seen after the first treatment.
Costs

Over-the-counter bleaching systems are the least expensive option, with costs ranging from $20 to about $150. Depending on where you live and the extent of the procedure, dentist-supervised home bleaching systems range in cost from approximately $150 to $300 per upper or lower set of teeth, or $300 to $600 for the whole mouth. In-office bleaching procedure range in cost from $200 to $500 per arch, or $500 to $1,000 for the whole mouth.

Supervised versus unsupervised process

Dentist-supervised at-home bleaching and in-office treatment offer additional benefits compared with over-the-counter procedures. First, your dentist can perform an oral examination and consider your complete medical history, which can be helpful in determining how your teeth became discolored and if bleaching is an appropriate course of treatment based on your type of stains and number, type, and location of restorations. Your dentist can then better match the type of stain with the best treatment, if appropriate, to lighten those stains. With dentist-supervised bleaching procedures, your dentist will likely want to see you a couple of times to ensure you are following directions, to make sure the customized tray is fitting properly, to inspect your gums for signs of irritation, and to generally check on how the teeth whitening process is proceeding. With over-the-counter bleaching products, you are on your own.

Caring for Your Dentures

Proper denture care is important for both the health of your dentures and mouth. Here are some tips.

Handling dentures

Stand over a folded towel or a full sink of water to help avoid damaging your dentures if dropped.

Brushing/rinsing

Dentures must be brushed daily to remove food and plaque and to help prevent permanent stains. Use a soft bristled brush specifically made for cleaning dentures. Don’t use a hard-bristled brush; it can damage dentures. Gently brush all surfaces. Be careful not to damage the plastic or bend attachments. Rinse your denture after every meal. Although you can use an ultrasonic cleaner, daily brushing is still a must. (Ultrasonic cleaners are devices that use sound wave to dislodge food and other deposits from dentures while they sit in a tiny tub of cleaning solution.)

Denture cleansers

Use hand soap or mild dishwashing liquid to clean your dentures. Toothpastes and household cleansers are too rough on dentures. Do not use bleach to clean your denture. It can whiten the pink portion of the denture. When not worn, dentures should be placed in water. This keeps them moist, which helps keep them from losing their shape. Your dentist can recommend the best methods for caring for your particular denture. Dentures should never be placed in hot water, as it can cause them to warp.

Denture repair

Never attempt to repair or adjust or your dentures yourself. Bending any part of the clasp or metal attachments can weaken the metal. Don’t buy over-the-counter repair kits or glues either. These can cause permanent damage to your dentures and glues may not be safe. Wait. You will be seen by your dentist or prosthodontist;(a dentist who specializes in the restoration and replacement of teeth) soon after receiving your dentures. If you think you need to be seen before your scheduled appointment, call your dentist.

Other frequently asked questions:

What if I feel that my dentures aren’t fitting right?

Dentures That don’t fit properly can cause irritation and sores in your mouth or on your gums. Call your dentist immediately if your denture breaks, cracks, chips or if one of the teeth becomes loose.

Will my dentures need to be replaced?

Because of the wear-and-tear on denture over time plus natural age-related changes to your face, mouth, jaw bones and gums, your denture will need to be relined, rebased or remade. Any of these types of fixes will also need to be made if dentures become loose. To reline or rebase a denture, the dentist or prosthodontist ;refits the denture base or makes a new denture base and reuses the existing teeth. Generally, complete dentures can be worn for 5 to 7 years before replacing them.

If I properly clean my dentures, what else should I do to maintain excellent oral hygiene?

Whether you have full or partial dentures, you should use a soft-bristled brush and brush your gums, tongue and palate (roof of your mouth) every morning before you put in your dentures. This removes plaque and stimulates circulation in the mouth. Be sure to clean the teeth that fit under the partial denture’s metal clasps. Plaque that becomes trapped under the clasps will increase the risk of tooth decay. If you wear a partial denture, remove it before you brush your natural teeth. Clean, rest, and massage the gums regularly. Rinsing your mouth daily with lukewarm salt water will help clean your gums. Never sleep with your dentures in place. Eat a balanced diet so to help keep your body healthy, which will help keep your mouth healthy too.

How often should I see my dentist?

Every 6 months is the standard routine unless otherwise told by your dentist. Regular dental visits are important so that your denture and mouth can be examined for proper denture fit, to look for signs of oral diseases including cancer, and to have your teeth professionally cleaned.
