The much anticipated day has arrived: your child's braces have been removed. You are really happy with the way your son's or daughter's smile looks now. All the time, money, and discomfort of having teeth straightened have been well worth it.
But did you know that the teeth could relapse into their old positions if your child doesn't wear a retainer every night?
Why is wearing a retainer necessary?
It is important for both you and your child to understand the reason for wearing a retainer. It has to do with how orthodontia works in causing teeth to move to more satisfactory positions.
The reason that orthodontia (“ortho” – straight, “odont” – tooth) works is that the tissues holding teeth in place are living and keep remodeling themselves. Teeth are suspended in the jawbone by the periodontal ligament (“peri” – around, “odont” – tooth), which suspends the tooth by extending from the cementum of the tooth on one side into the bone on the other. Cementum is the thin layer of calcified tissue covering the dentin of the root. When light forces are placed on it, the periodontal ligament can reform itself and adapt to the pressures it is under.
Orthodontists know how to keep the pressures during orthodontic treatment light enough to cause movement that is slow and steady but not so strong that the tissues are damaged. If too much force is applied, the process can cause damage to the periodontal tissues and tooth roots.
When the teeth have moved to their desired positions, they will continue slowly moving. The purpose of a retainer is to stabilize the teeth in their “finished” position. They must be retained in this position long enough that the bone and ligament can completely re-form around them, a process that can take several months.
Make it clear to your child that a retainer won't have to be worn forever. Once your child understands that it is very important to wear the retainer for a few months in order to stabilize that attractive new smile, it should be easy to convince him or her to use it nightly.
If you believe you need a crown or if we have already confirmed this fact, you need to understand that there are several options. The most common are gold crowns, porcelain-fused-to-metal crowns and all porcelain crowns. Each has both pros and cons; thus we will work with you to determine which will work best for your specific needs. However, to help you learn more now, here are some facts.
Made from cast gold, this type of crown has been around for over 100 years and is the most successful type of crown. It can last more than 50 years and thus many dentists prefer gold restorations for their own teeth, where cosmetics is not a concern.
All Porcelain Crowns
All porcelain crowns can produce an incredible, life-like appearance. However, because they are made purely from dental porcelain (a type of glass), they tend to be more fragile than gold crowns and may be more at risk with certain high biting forces. Thus they may not be as durable. Porcelain can also cause wear to the natural teeth they bite against. Therefore they are typically preferred for front teeth, rather than back teeth. They have an aesthetic longevity of about 10 years and a functional longevity of about 20 years.
As the name states, porcelain-fused-to-metal (PFM) crowns provide the best of both worlds. They are made of natural tooth-colored dental porcelain that is fused on top of a precious or noble metal (usually gold or platinum). They are stronger than porcelain alone and are a good option for back teeth because they offer a better cosmetic result than gold crowns. This is also true for front teeth, however the gold support beneath the porcelain can compromise its life-like qualities. These crowns also have a proven track record and have been used with excellent results for over 40 years.
Your smile is one of the first things people notice, but if your pearly whites have lost their luster, chances are you might be hesitant to show them. As we age, our teeth naturally darken, and certain substances can leave teeth stained or discolored, making you appear older. One easy way to turn back the clock is to have your teeth whitened; a safe, painless, and non-invasive way of achieving a young, healthy-looking smile.
Causes of Tooth Discoloration: Exposure to high-levels of fluoride and taking tetracycline antibiotics during childhood can stain the teeth's structure. Smoking cigarettes and using chewing tobacco can also cause tooth discoloration, as well as foods containing tannins such as red wine, coffee and tea. In addition, poor brushing techniques and not flossing regularly cause bacteria to build on teeth resulting in yellow stains.
The Whitening Process: Our office can help you to achieve a brighter smile using either an in-office procedure or an at-home whitening kit. We can help determine the best treatment for your budget, time frame and individual needs. If you choose to have professional whitening done in our office, we will utilize a prescription strength gel sometimes even activated by a concentrated light source. This procedure offers immediate and long-lasting results in less than an hour. After a single treatment, teeth are typically six to ten shades lighter and with proper maintenance, can last five years or longer.
At-Home Results: For those seeking more gradual results, another option is to use custom-fit trays, which our office will make for you to use at home to whiten your teeth. This is generally less expensive, and is very effective at lightening teeth several shades, although it may take a week or longer to see optimal results.
Choosing the Best Procedure: For some people, teeth whitening may not offer adequate results. If you have thin enamel, chipped, uneven or crooked teeth, we may recommend applying porcelain veneers to restore your damaged teeth. Veneers are bonded to the front of teeth to give your smile a straighter, more uniform appearance.

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.
