It has been said that the most important fashion accessory you can wear is a smile. One way many people choose to improve the look of their smile is through whitening their teeth. Teeth whitening is the most frequently requested dental procedure and has become a multi-billion-dollar industry.
Options to whiten teeth include over-the-counter products or professional whitening at the dentist. It is best to consult a professional first when considering any procedure that involves dental health. Dentists will be able to explain the available methods, helping patients choose the fastest, safest, and most effective method to brighten their smiles.
Why Aren’t My Teeth White Anymore?
Over time, you may notice your teeth becoming dull and changing color. Shades of yellow, brown, and even grey are not uncommon. Several factors can contribute to your teeth losing their luster. The causes can be divided into two types—intrinsic (internal) and extrinsic (external.)
Intrinsic causes of tooth discoloration include heredity, aging, tooth decay, and overexposure to fluoride. Intrinsic stains are least likely to be helped with whitening agents.
Extrinsic causes come from external sources, some of which are avoidable and others that are not. Things like coffee, tea, wine, and tobacco will stain teeth. So will certain diseases and medications, particularly antibiotics.
Typically, teeth whitening has better results tackling problems caused by food, drink, and smoking than by medical issues and genetics. Teeth with yellow discoloration respond best to whitening agents. Some brown or grey teeth, unfortunately, may not be able to be whitened.
Options for a Brighter Smile
Teeth whitening products use a peroxide solution to bleach the teeth. Many local drug stores sell a variety of products at reasonable prices. Some are more effective than others. Patients can spend a lot of time and money searching for something that works.
Patients can also get teeth whitening from a dentist instead. The dentist can either administer the whitening agent in his or her office, or will offer customized products to use at home. Teeth whitening with a dentist is typically more expensive than over-the-counter options, but having a professional supervise the process has its advantages. Dental practices will be able to provide information about the cost as well as success rates. Online patient reviews may also be a good source of information.
Choosing to Do Teeth Whitening Yourself
At-home teeth whitening is widely advertised and readily available. It takes the form of:
- Whitening toothpaste
- Whitening mouth rinses
- Gel strips (plastic strips that stick to your teeth)
- Whitening trays (molds that are filled with whitening gel and placed over the teeth)
Toothpaste and rinses may help with some minor surface staining on the teeth if used regularly. Gel strips and whitening trays tend to have better results. Results vary widely though, and it may take numerous applications before there is any noticeable improvement.
These products are a popular option for many consumers. They are inexpensive and they don’t require a visit to the dentist. But an appointment with a professional can help zero in on the whitening method that will work best for a particular issue. That can save time and money, and get better results in the long run.
Why a Professional May Be Better
If stains are resistant to at-home treatments, consider teeth whitening with a dentist.
Because the process is supervised by a professional, a much stronger solution can be used. Over-the-counter products contain 3 to 20% hydrogen peroxide solution, while dentist-administered whiteners contain 15 to 43%.
Since the whitening agents used are stronger, they work more quickly. Results can be visible immediately after one 30 to 60-minute treatment. After several visits, patients report that their teeth are 3 to 8 shades brighter.
It is very important that teeth are healthy before using teeth whitening products on them. Using strong chemicals on teeth with cavities or cracks can be extremely painful and cause further damage. Under the supervision of a dentist, any problems can be found and fixed before beginning treatment.
A Dentist Can Help You Avoid the Pitfalls
Not only can dentists achieve faster and more noticeable results, they can also take steps to avoid some of the mistakes that can happen with do-it-yourself products.
Teeth whitening is safe when done correctly. But the chemicals used in teeth whitening can be harsh on gums, especially if they are already sensitive. Dentists take special precautions to protect your gums during the process.
If using over-the-counter whitening trays, they are “one-size-fits-all.” Since they may not fit over the teeth perfectly, they can rub and irritate your gums. A dentist can provide customized trays for a personalized fit.
It is also possible to over-use whitening products. Overuse can cause softening of the teeth’s enamel, which can lead to cavities. Teeth whitening with a dentist ensures the proper amount of chemicals for the right amount of time.
Patients with fillings or crowns that match the color of your teeth need to know that tooth whiteners don’t work on these materials. Too much whitening can make teeth end up whiter than the dental work, causing them to stand out instead of blending in. A dentist will make sure this doesn’t happen.
What Happens During Teeth Whitening With a Dentist
Here’s what to expect when visiting a dentist office for teeth whitening:
- First, the dentist will prepare the teeth with a thorough exam and cleaning.
- Next, a liquid, rubber-like resin is applied to the gums to protect them from the harsh whitening chemicals.
- The whitening agent – usually a hydrogen peroxide bleaching gel – will be applied to teeth and allowed to sit for 15 to 30 minutes. A device might be used to shine a light on the teeth to help activate the process.
- The whitening agent is cleaned off and reapplied, sitting for another 15 to 30 minutes.
- This final step may be repeated a few more times at each visit.
- Additional visits may be required until teeth reach the desired brightness.
Is Professional Teeth Whitening Worth It?
Teeth whitening with a dentist may cost more, but it has become a popular way to brighten a smile. Stubborn stains and sensitive gums are the two main reasons why a dentist may be the best choice. Having a professional oversee the process can ensure it is safe and comfortable. Many people agree it is worth the extra cost.
