If you cringe at the appearance of your less than pearly whites when you look in the mirror, you are not alone. A frequently requested cosmetic procedure, teeth whitening is a very successful and relatively inexpensive way to enhance your smile. We can determine which whitening treatment will work best for you after performing a basic oral examination in our office. When will it work and when won't it? Here's some background:

Teeth most commonly become stained or discolored due to surface (extrinsic) changes, the most common of which are dietary and smoking. Foods including red wine, coffee, and tea can cause extrinsic staining. Teeth can also commonly become discolored or stained due to intrinsic (internal) reasons, such as changes in the structure of enamel or dentin or by incorporation of chromogenic (color generating) material into tooth tissue during formation or after eruption.

1. Toothpastes that claim to whiten teeth are only effective in removing plaque and other surface stains. Although most of these products contain mild abrasives that remove the plaque, they aren't capable of changing the underlying color of stained teeth.
2. Tooth polishing by your dentist or dental hygienist is effective in removing superficial staining, but will not change tooth color.
3. Teeth whitening systems work by bleaching, generally with the use of hydrogen peroxide. Using bleaching gels in custom made trays or whitening strips can be done at home, but is slow and the changes are gradual. We can perform quicker and more effective “power bleaching” in our dental office when precautions can be taken to ensure safety due to the higher concentrations of bleaching gels used. Teeth with intrinsic (internal) staining may need internal bleaching to whiten them and this can only be done in the dental office.
4. Teeth whitening results fade over time, but optimally last from six months to two years. Taking care of your newly whitened teeth by avoiding the foods, beverages, and habits that cause staining will help them remain whiter for longer.
5. If you have had previous cosmetic dentistry performed, including the placement of composite restorations, porcelain veneers, or crowns, teeth whitening may not be for you. Bleaching agents have little to no effect at all on the materials used to create these restorative products.

If you are pleased with your smile except for that one front tooth that appears darker, then we have good news for you. Often a tooth appears darker as a result of trauma that may have occurred years ago. Your tooth may need root canal treatment or may have already had root canal treatment in the past. Regardless, you can whiten this tooth via a process called internal bleaching. And as the name suggests, the tooth can be bleached from the inside out. Here's a brief summary of how this entire process works:

1. Performing an x-ray exam: The first step is to take a radiograph (x-ray) to make sure that your root canal filling is intact adequately sealing the root canal and the surrounding bone is healthy.
2. Making an access hole: To apply the bleaching agent, a small hole will need to be made in the back of your tooth to apply the bleach. However, before doing that, the area must be thoroughly cleaned and irrigated.
3. Sealing above the root canal filling: This step is critical to prevent the bleach from leaking into the root canal space.
4. Applying the bleach: To obtain the whitening needed, it typically requires between one and four office visits for additional bleaching.
5. Applying a permanent restoration: Once your tooth has lightened to the desired color, a permanent filling will be placed over the small hole to seal your tooth's dentin. This is then covered with tooth-colored composite resin (filling material) so that the access hole is undetectable to the naked eye.

Time to tune up the brightness on your teeth? Here are six modern methods of whitening and brightening your smile.

• In-office “power” bleaching under the supervision of my staff and me is recommended if your teeth are badly stained, or if you are about to have veneers or crowns made. It's quick, safe, and effective. Gels containing high concentrations of bleach are applied to your teeth in our office, often with the enhancement by heat and light to make them act faster. Results show teeth becoming up to ten shades lighter in about an hour.
• “Take home” whitening solutions and trays are designed to fit your mouth and can also be provided by my office. The technique is easy to perform and is less expensive than in-office power whitening system, although it takes longer to see the same results. General recommendations are for 30 minute applications twice a day. You can usually see a change after two to four sessions. This requires patience, because it is important not to exceed recommended exposure in order to avoid damage to your teeth, gums, and the inside skin of your mouth. After two weeks of use, teeth can be expected to be about eight shades lighter.
• Whitening strips look like clear Band-Aids that are applied to the tooth surfaces. They should be worn twice a day for 30 minutes each time, for seven days. On average, they claim to lighten teeth more than three shades. They take about two weeks to work at 30 minutes per day.
• “Paint on” or “Brush on” whitening formulas are also available. These are gels that are painted onto the teeth every night at bedtime, for two weeks. Some claim that this line of home whitening can whiten teeth two to five shades. These gels may make your mouth feel goopy, but they are relatively inexpensive. Some gels come with a small brush to scrub them onto the teeth.
• Over-the-counter “mouth-tray” whiteners use mouth trays that are not designed for your particular mouth, so they may not fit well and may be messy or uncomfortable. They are filled with gel and worn 45 minutes a day for one week. On average, teeth become two shades whiter.
• Whitening gum is a relatively new product. It requires chewing two pieces for at least 20 minutes, four times a day, to see an effect.

Whitening your teeth is an easy way for most people to achieve a brighter, more appealing smile. And for older adults, it can also contribute to a more youthful appearance. We are often asked how our tooth whitening products and services stack up when compared to the many over-the-counter (OTC) products available at discount and drug stores. The following are some key facts to understand about teeth whitening so that you can receive the results you want.

What is the real difference between professional products and ones I can buy over-the-counter?

Whether you purchase over-the-counter whitening strips, toothpaste, mouthrinses, or “paint on” tooth whitening products, you are basically receiving the same product, but with a lower concentration of carbamide peroxide, the chemical responsible for teeth whitening. And while some of the products may contain a slightly higher concentration of this solution, they all are under strict governmental guidelines for ensuring you experience little to no side-effects as long as you follow the instructions. However, with our bleaching products and services, you are under the care of a trained professional and thus can receive much higher concentrations without compromising your health or the health of your teeth. This fact means that under our care you can achieve more dramatic results faster.

How long will the results last?

Bleaching is not a permanent solution; thus, your results will diminish over a six-month to one year period of time. However, it doesn't take much to touch up or maintain your white smile in a single visit, or with custom-made whitening trays that we can provide for home use. You can also keep your brighter smile a little longer by avoiding food that stains your teeth. And when drinking coffee, tea, cola, wine and other drinks like these, sip them using a straw so that they are less likely to discolor your teeth.

Is bleaching safe for my teeth?

We pride ourselves on providing and promoting optimal oral healthcare and thus would never offer any products or services that are unsafe. Additionally, there are numerous studies supporting the overall safety of whitening your teeth. We are careful to avoid sensitivity, which is an occasional side effect of intensive bleaching, and we suggest protecting the teeth with fluoride.
