Professional Whitening Services

When talking about teeth whitening, we can all agree a whiter, brighter smile is pretty awesome.

Today, tooth brightening products are no longer exclusive to in-office dental whitening treatments.

Teeth whitening products are now very affordable and can be purchased in most grocery stores and supermarkets.

However, before I dive into the best whitening products for you, let’s cover a little background about teeth in general.

Before you buy whitening products, it is important to understand how these bleaching products work and why you need to research the safest ones for your teeth.

Why teeth darken with age?

As we age, the outer coating of enamel on your teeth wears away with age, revealing the yellow dentin.

Your tooth dentin also expands with age, reducing the size of the pulp. The tooth’s translucency decreases, making it appear darker.

Your tooth enamel is extremely strong, but it is very important to take measures to protect it. You can safeguard your tooth’s enamel by:

  • Brushing regularly (but gently)
  • Limiting the amount of acidic foods you eat, such as fruit juices
  • Treating acid reflux condition
  • Cutting back on excessive soda consumption
  • Avoid excessive amount of vitamin C

Does tooth whitening damage teeth?

The most obvious indication of damaged enamel is a yellow discoloration of your teeth. This raises the issue, “Do teeth whitening products harm enamel?” The answer is no, teeth whitening does not damage your tooth enamel.

The dentin, or major component of the tooth, is the section of the tooth that is responsible for the color of your teeth. The front surface of the teeth is initially covered with a whitening solution.

The solution will then pass through the enamel of the tooth to reach the dentin. The inner layer’s discolored tissue will begin to fade.

This is the teeth whitening process for the majority of whitening gels and strips on the market today.

There are two main products used for teeth whitening

The two most common tooth whitening products are hydrogen peroxide and carbamide peroxide.

Unlike whitening toothpaste, which utilizes abrasives to mechanically remove surface-level stains, the oxygen molecules in these whitening chemicals weaken your teeth stains on a molecular level.

A form of peroxide is also used in several over-the-counter (OTC) whitening strips, kits, and pens. The chemical concentration level is what distinguishes them from most professional teeth whitening services.

In-office dental whitening

For in-office dental whitening, dental professionals use a very high percentage of hydrogen peroxide. These products are typically stronger than OTC (over-the-counter) products. During the procedure, they use a special rubber guard to protect gums. If peroxide gets onto the gums, it will burn them.

Like at-home whitening products, there are a wide variety of professional teeth whitening methods to choose from. In-office professional whitening results will be visible quicker, but definitely a costlier way to brighten up your smile.

The majority of patients seeking professional teeth whitening will receive custom take-home trays. This process falls somewhere between consumer-grade whitening products and the highest end of whitening services available.

Again, the biggest differences between at-home and in-office services are; the strength of products used for whitening, the speed at which you will see results, professional oversight of the process, and overall cost.

In office whitening treatment – What to expect

To protect the gum tissue from any discomfort caused by the bleaching gel, a liquid rubber barrier or hardening resin is put over it. A hydrogen peroxide bleaching gel is administered to the teeth and left on for 15 to 30 minutes.

Here are the two most common teething whitening methods used for in-office treatments:

  • The more traditional procedures involves placing the hydrogen peroxide gel on teeth for period of time. This is very similar to many at-home whitening products you may have used, except the gel is stronger
  • The second whitening treatment method still uses the gel, but your mouth is kept open and teeth are exposed to a high-intensity light source.

Studies have shown the effect of light-activation sources on tooth bleaching produces mixed results.

I have tried both of these in-office whitening processes and was very pleased with the results.

Over time, additional tooth whitening was needed, and sought alternatives to teeth whitening than what I previously tried.

Take home whitening kit from dentist

While in-office whitening is quick, personalized take-home trays need some effort on the part of the patient.

If your dentist feels your smile is prone to new stains, they may be your primary treatment recommended in-office whitening visits.

What to expect

Your dentist will use a professional take-home-tray to produce an impression of your teeth for a custom-designed tray.

This personalized tray will often provide better whitening effects than OTC trays since it will fit properly to the structure of your mouth.

Instead of a hydrogen peroxide-based gel, you’ll most likely be given a carbamide peroxide-based gel to use at home.

Although it does not whiten as rapidly as a hydrogen peroxide-based gel, it is less likely to cause discomfort if it gets on your gums, cheeks, or tongue.

According to the American Dental Association, the concentration of the gel your dentist offers you for your custom-fit trays ranges from 10% to 38% carbamide peroxide.

The duration of your treatment will also vary, with you wearing your tray for two to ten hours every day, for up to 28 days. Carbamide levels in over-the-counter trays are comparable.

The difference in quality lies in the fit. A custom-designed tray will fit snugly around your teeth, leaving little leeway for the gel to creep up to your gums or miss whitening difficult-to-reach nooks.

Is professional teeth whitening worth it? In-office vs At-home

While both at-home and in-office whitening are successful when performed under the guidance of your dentist, there are a few key differences.

In-office whitening procedures are normally completed in one or two sessions, depending on the severity of your stains and your dentist’s opinion on how many shades whiter your teeth may become.

Each session lasts no more than 60 to 90 minutes. Meanwhile, you’ll have to wear your custom-made take-home trays for up to a month.

Your dentist may prescribe a custom-fit tray for touch-ups even after in-office whitening for optimal results.

How long does teeth whitening last

Because there are so many teeth whitening methods, average tooth whitening results can last anywhere from six months to three years. However, in most situations, people see improvements that last approximately a year.

There is no such thing as an everlasting teeth whitening treatment. But you still want to do all possible to keep your pearly teeth gleaming for months and years to come.

Experts advise maintaining a strict dental care regimen, avoiding brightly colored meals, coffee, red wine, and soda, and utilizing over-the-counter touch-up solutions.

There is no definitive answer as to which treatment will last the longest, however, with custom trays, frequency is critical.

At-home trays can be worn on a regular basis for up to three to five years, whereas an in-office visit can be completed in one or two sittings.

This implies that the brilliant color of your teeth when using trays may last longer because you are able to request a professional whitening solution from your dentist to be used at home.


Custom, take-home whitening trays are less expensive than in-office whitening, but they are still more expensive than over-the-counter trays and other at-home whitening solutions.

They normally run between $300 and $600. In-office whitening, on the other hand, costs $800 to $1,000.

Teeth whitening is not covered by dental insurance because it is a cosmetic procedure.

In-office Professional Teeth Whitening Alternatives

For many people, at-home teeth whitening is a good, cost-effective choice. It’s inexpensive and has little to no tooth sensitivity.

The final conclusion is that at-home whitening solutions are a more affordable, convenient, and great choice.

Furthermore, there is a wide variety of teeth whitening formats to pick from—toothpaste, whitening strips, pens, and more—to suit any desire.

Teeth whitening sensitive teeth

Sensitive teeth are frequently caused by receding gums, gingivitis, or damaged teeth.

This complicates teeth whitening, which is why it’s a good idea to see your dentist before beginning any whitening treatment.

how to use teeth whitening strips

Because your dentist is the most knowledgeable about you and your dental history, she can work with you to build the most effective and pleasant alternative for whitening sensitive teeth when the time comes.

Those with sensitive teeth should opt for whitening treatments that don’t require significant application time. Some solutions, such as Crest 3D White Whitestrips Gentle Routine, take only five minutes every day to remove tooth stains.

It is particularly intended for those who have sensitive teeth to whitening and contains the same substance that dentists use in a less intense version.

Brush your teeth with Crest Gum and Sensitivity Gentle Whitening Toothpaste, which has a special mix that helps you preserve your newly whitened smile while guarding against sensitivity suffering.

This more subtle whitening technique removes stains from the teeth and whitens them via deep cleaning.

Fact – 40 million Americans will suffer from bruxism (tooth grinding). The repercussions of stress, worry, or an aberrant bite can be catastrophic.

Grinding your teeth at night can cause insomnia, a painful jaw, and dull headaches. Your teeth wear down over time (attrition), become extremely sensitive, and may require considerable dental repair.
