Safe and effective teeth whitening is dentist supervised

Most people would welcome the chance to have a whiter, brighter smile. But in the quest to get their teeth super white, some people use bleaching gel over and over again. Is it possible to over bleach your teeth?

Teeth whitening can be fun and rewarding. But overdoing it can lead to sensitivity, pain, and some surprising but disappointing results. What are the effects of overdoing it?

Results of Whitening Your Teeth Too Frequently

  • Tooth roots – Excessive teeth whitening can damage teeth and their roots. When teeth are whitened too frequently, damage to the tissue around them can create the need for root canal treatment. Also, too much whitening gel can cause chemical burns on your gums.
  • Tooth enamel – Excessive bleaching can wear away tooth enamel and give your teeth a gray or blue hue. You can lose your super white teeth and cause them to turn dark and unattractive. In severe cases, cosmetic dentistry will be needed to conceal the dark color.
  • Sensitivity in teeth – Some people who over-bleach their teeth have difficulty tolerating cold or hot food or drinks. Tooth nerves can become irritated and send radiating pain throughout your teeth.

It is always best to check with your dentist before whitening your teeth. If you have cavities developing, the gel can irritate them. And in some cases, teeth whitening will make stains on your teeth even more noticeable.

A cosmetic dentist can examine your teeth and anticipate the effects of the bleaching gel on your teeth and gums and let you know if it’s the right treatment for you.

Everyone who whitens their teeth without the assistance of a dentist should take the necessary precautions to ensure the whitening gel used is FDA approved and not a cheap knock-off that will damage teeth.

Can I get my teeth white while I am wearing braces?


I really should have gotten my teeth whitened before I got braces. I don’t know why I didn’t. I just kept putting it off. Thanks, M.A.

M.A. – Yes, it is possible to whiten teeth while you are wearing braces, but it may be best for you to wait until your braces are removed. There are several factors to consider.

Teeth Whitening While You Wear Braces

  • Certain brands of teeth whitening have whitening trays that are made to fit over braces. The whitening gel will get beneath the braces to whiten your teeth, but it may not get beneath the brackets that are bonded to your teeth. When your braces are removed, your teeth will look patchy.
  • Many dentists don’t recommend whitening your teeth while you wear braces. Many whitening products, including whitening toothpaste, scratch ceramic braces.
  • It is easier to whiten teeth during orthodontic treatment if you wear Invisalign. The invisible braces are easily removed, so whitening your teeth will work well and evenly. For patients who wear Invisalign, your dentist will tell you the best time to begin whitening your teeth.

Speak with the dentist or orthodontist from whom you received the braces to determine if you are a candidate for teeth whitening. Do not try to whiten your teeth yourself without speaking with your dentist about it first.

Your dentist will also give you tips on how to avoid staining your teeth while wearing braces.

Four Things to Know about Teeth Whitening Parties Before Accepting the Invitation


I received an online invitation from a friend to a teeth whitening party at a friend’s house. The entire thing is supposed to last about 4 hours. I am not sure about the company that is offering the whitening because I can’t find any information about it online. The invite looks very professional and it says that we will keep the gel on our teeth for 45 minutes to an hour and my teeth will be whiter when I leave. Is this something done that dentists are doing that you know of? It sounds like a dental house call for a group of people. The price is $145 per person, which is cheaper than what my dentist is offering. Is it safe? – Yanika

Yanika – If you received an invitation for a teeth whitening party with no clear information about the sponsor, beware.

Some Facts about Home-Based Teeth Whitening Parties

Teeth whitening trays keep gel on your teeth

A teeth whitening party lacks the ability to provide some common-sense precautions to ensure you get safe, predictable results:

  • Examination – A dentist examines your teeth in advance of teeth whitening to determine if you are a candidate for it. For some people, bleaching gel makes stains in teeth more noticeable. Others experience a lot of sensitivity. Only an examination by a dentist can anticipate the results you will get from teeth whitening.
  • Proper sanitation and monitoring – It is difficult to monitor a group of people who are getting their teeth whitened. Do you know who will be doing the whitening, and what will be used to whiten your teeth? Will the environment be sanitary for your oral health?
  • Effective whitening – Professional treatment includes customized bleaching trays to keep the gel in contact with your teeth and away from your gums. There is no way you can receive custom trays at a four-hour teeth whitening party.
  • Follow-up – Dentists schedule follow-up appointments to ensure the results are as expected and your teeth and gums are healthy. At times, more sessions are needed to ensure your teeth are as white as you want them.

If you really want your teeth whitened, we advise asking your dentist or a dentist who offers it. This is the only way you can be reasonably sure that you will receive quality treatment.

What’s the safest, cheapest DIY teeth whitening?


I really want my teeth whitened, but I don’t have a lot of extra money. In September, I graduated university, and I’ve had to pay for my own education. Any extra cash is going toward payment of student loans. When I have any extra money, I can’t justify using it to whiten my teeth, but I do want a bright smile. I’m sure it will help my career. Before I waste money on cheap online kits or stuff that they say is free online, I want to know what really works. Is there any safe teeth whitening product that I can get cheap or free? Kamrin

Kamrin – Before we answer your question, we want to ensure you understand: The safest way to brighten your teeth is under a dentist’s supervision. If you do it yourself, the results are unpredictable.

It is possible to get limited results with inexpensive teeth whitening. But don’t expect a super-white smile. The ingredient to look for in effective whitening gel is carbamide peroxide. If you have sensitive teeth, find gel with a lower percentage of the ingredient.

Tips for DIY Teeth Whitening

  • Over-the-counter whitening strips – They can be effective. Check for the amount of carbamide peroxide in the strips. The higher the percentage, the more powerful the strips. But the more powerful strips may cause sensitivity in your teeth. If you experience sensitivity, take a break from the gel for a few weeks before using it again. You can also consider using strips with a lower percentage of carbamide peroxide. You may have to use whitening strips longer than two weeks to get the best results. Wait at least two weeks before using a new box of strips for another round of whitening. It will allow time for the color of your teeth to stabilize.
  • Discounted whitening from a dentist – There are some dentists that offer discounted teeth whitening to their existing patients who keep their dental cleaning and exam appointments. You may have to establish yourself as a regular patient before receiving the whitening treatment. Some dentists who don’t offer discounts provide a payment plan for the treatment.
  • Free or online kits – Avoid online kits that are advertised as free. These often are ineffective, damage your teeth, or have very high shipping fees. It is difficult to verify the active ingredient in free bleaching gel, so it’s best to stay away from it.

Before You Whiten Your Teeth

Teeth whitening trays keep gel on your teeth

Before you begin whitening your teeth, ensure that they are free of decay and your gums are free of disease. If your oral health isn’t good, the whitening gel can cause irritation. Dentists look for the causes of stains in your teeth to determine if they should be bleached.

If you decide to use bleaching gel that comes in tubes, only use it with customized trays. The trays keep the gel in contact with your teeth and away from your gums.

Teeth whitening scam with crazy shipping charges


Every now and then I search for deals on teeth whitening. I finally found one that sounded good. It was for a month trial of whitening and all I had to do was pay shipping and handling. The cost for shipping was posted on the website as $9.99. I thought that was pretty expensive but compared to free whitening I thought it was nothing. Within the last 2 months, I’ve received 3 charges for shipping and handling, but I still don’t have the whitening kit. My credit card company is investigating it now. I just want to know where I can get legitimate, free teeth whitening trials. Do you have any recommendations? Todd

Todd – We’re sorry to hear about your experience. Unfortunately, it is common. There are some risks that come with getting free teeth whitening online. What should you consider?

Beware of Getting Free Teeth Whitening Online

  • Source – On the website, instead of a business address, there is usually only a toll-free number or a contact form if you need to speak with someone at the company. The website probably doesn’t tell you the source of the whitening. If you call the company, you are unlikely to find out exactly where the whitening kit was made.
  • Contents – How do you know if the syringes really contain bleaching gel? Some consumers have found out that the contents were either ineffective or harmful to their teeth.
  • Results – If what you receive isn’t bleaching gel, either it won’t work, it can harm or discolor your teeth, or it can burn your teeth, gums, or other oral tissue.

If your dentist doesn’t offer free teeth whitening, ask for a payment plan to make it more affordable for you. It’s best to receive quality bleaching gel, along with supervision from your dentist. You’ll get predictable results that will last.
