What Causes Tooth Discoloration?

Teeth inevitably become discolored over time, which is a natural part of aging. There are two types of tooth discoloration, including extrinsic and intrinsic staining.

glass and mug of coffee

Extrinsic tooth discoloration affects the outside of teeth. Certain foods and beverages such as tea, soda, red wine, dark berries, and coffee cause this type of discoloration. These stains can be easily removed with at-home whitening products.

Intrinsic discoloration develops on the inside of teeth. It can be caused by certain diseases and medical treatments (like chemotherapy), genetics, trauma, medications, and aging. These stains are more difficult to remove and typically require professional teeth whitening. 

Fortunately, there are many ways to whiten your teeth without having to give up your favorite foods.

hismile PAP+ Teeth Whitening Kit™

hismile PAP+ Teeth Whitening Kit™

Best for Sensitive Teeth

hismile's teeth whitening kit uses three powerful, enamel-safe ingredients to provide instant results without any sensitivity:

  1. Hydroxyapatite (nHAp) rebuilds the protective layer of teeth and replaces lost minerals.
  2. Phthalimidoperoxycaproicacid (PAP) is clinically proven to whiten teeth without sensitivity or gum irritation.
  3. Potassium citrate helps relieve pre-existing sensitivity and provides long-term protection.

These Whitestrips were developed to provide a comfortable at-home whitening experience for people who have tooth sensitivity but still want to brighten their pearly whites. These enamel-safe strips get applied for 30 minutes daily.

Cost: $

Colgate Optic White

Colgate Optic White Advanced Whitening Toothpaste

Best Whitening Toothpaste

The product contains 2 percent hydrogen peroxide, which dentists recommend for whitening. It also contains fluoride to protect against cavities. 

Whitening toothpaste is not as effective at whitening your teeth as LED kits or Whitestrips. But it can help remove and prevent surface stains. Therefore it should be used in addition to one of these other methods.

Cost: $

Colgate Optic White Mouthwash

Colgate Optic White Whitening Mouthwash

Best Whitening Mouthwash

Colgate Optic White Whitening Mouthwash contains 2 percent Hydrogen Peroxide. This can slightly help remove surface stains. However, whitening results from mouth rinse alone will not be as effective as an LED whitening kit or Whitestrips.

Because it does help prevent new stains, whitening mouthwash is best used in addition to another whitening product.

Cost: $

colgate led teeth whitening kit

Colgate Optic White Advanced LED Whitening

Best All-in-One Whitening Brand

This LED whitening kit was designed to reduce sensitivity and uses enamel-safe ingredients. If you're a fan of using the same brand for every step of your oral health routine, you can use Colgate whitening toothpaste, mouthwash, and LED kit.

This kit can be used hands-free and doesn’t require a smartphone to use it, making it easy to apply.

Colgate Optic White Advanced LED Whitening only takes 10 minutes a day for 10 days to see results. It is clinically proven to deliver brighter teeth up to 6 shades whiter.

Cost: $$$

Types of At-Home Teeth Whitening Products

People spend $3.2 billion on teeth whitening treatments worldwide.

Depending on your needs, budget, and level of discoloration, some common teeth whitening options include:

Whitening Strips, Toothpaste & Mouthwash

Whitening strips, such as Crest Whitestrips, make your teeth look whiter over time. They must be used consistently to see results.

Whitening strips contain a gel that is spread along the strip. This strip is placed onto the surface of your teeth for about 30 minutes. The gel is made of carbamide peroxide or hydrogen peroxide, which works to penetrate your tooth enamel and remove stains. 

Whitening toothpaste and mouthwash contain small amounts of peroxide. These products can effectively lighten teeth, but only about one or two shades. 

Whitening toothpaste can also be abrasive if overused, which can lead to enamel erosion or dentin exposure. Only use whitening toothpaste once a week or less to prevent these effects. 

Natural Teeth Whitening Products

Natural teeth whitening products do not use peroxide or chemicals to whiten teeth. These whitening products come in the form of toothpaste, mouthwash, gels, and strips. They usually contain essential oils, botanicals, and other natural ingredients to lift stains over time. 

Natural whitening treatments do not cause sensitivity (because they don’t contain carbamide peroxide) or increase your risk for tooth decay. This makes them a popular option among people who want to live a more toxin-free lifestyle. 

In addition to cleaner ingredients, natural whitening products are vegan, cruelty-free, fluoride-free, latex-free, sulfate-free, paraben-free, and gluten-free. They are also naturally sweetened with safer sugar alcohols, such as xylitol. 

LED Teeth Whitening Kits

LED teeth whitening kits are becoming more popular, and there are many brands to choose from today. These kits are also more effective than other at-home whitening solutions (e.g., whitening strips, toothpaste, and mouthwash). 

An LED light alone will not change the color of your teeth. It helps speed up the whitening process when combined with a tooth-whitening agent. When this interaction occurs, the blue LED light penetrates the enamel and lifts stains.

Whitening Gels & Pens

Whitening pens are ideal for people on the go. These compact whitening pens can fit in your bag, and only require a few minutes a day of whitening. They are also relatively inexpensive. 

While convenient, whitening pens must be used consistently to maintain results. You can also use them in combination with LED whitening kits or other products to keep your smile bright.

How We Rate and Review Products

All medical content on this site, including this guide and other product reviews, is written by our team of experienced writers and researchers. All NewMouth writers vet products that are recommended and reviewed in the industry. In cases where this is not possible, our team will:

  • Compare positive and negative reviews on the products
  • Talk to company leaders to ensure their products are safe and effective
  • Look into costs to ensure customers are getting the best quality products at reasonable prices
  • Read research studies to compare the pros and cons of each product

Every piece of content is heavily reviewed before publication. All content on NewMouth is also medically reviewed by a licensed dentist, specifically any content where we recommend products. Our dentists flag any recommendations they don’t agree with. Any products that don’t meet their professional standards are removed.

Many of the products we recommend have the American Dental Association (ADA) Seal of Acceptance. These products are proven to be effective in preventing gum disease, cavities, and other oral health conditions.

When we recommend products that do not include this seal of acceptance, we conduct further research to ensure reputability. This may include speaking with company leaders, reading hundreds of customer reviews, and ensuring they provide quality customer service.

Side Effects of Teeth Whitening

Sensitivity caused by whitening is typically mild and nothing to worry about. But if you experience severe sensitivity, you may be overusing whitening products.

"Over long periods of time, hydrogen peroxide at high doses can damage enamel," says Dr. Casey Lau, the Chief Dental Officer at Elims. "However, many studies have been done with hydrogen peroxide in dental products which showed that it is perfectly safe if used the correct way."

Some whitening toothpastes are highly abrasive and should not be used for more than 4 weeks. Doing so can lead to enamel erosion and damage. Abrasive particles like charcoal-based products are also not effective for whitening. They only remove stained plaque and do not penetrate the enamel. 

Instead, choose a whitening toothpaste that contains enzymes such as papain and bromelain. These enzymes are more effective at reducing naturally occurring stains than abrasive pastes.

In addition to sensitivity, other possible side effects of teeth whitening include:

  • Reversed whitening effects (teeth appearing more discolored than before)
  • Gum irritation (including ulcerations and burns)
  • Loss of tooth enamel (protective layer of teeth), which can lead to cavities
  • Increased risk of tooth fracture and damage

Note: these side effects can occur if you do not follow the manufacturer’s instructions. You may also have an allergic reaction, which can cause gum irritation.

How to Manage Sensitive Teeth

Sensitivity tends to disappear within a few days of whitening. The sensation is typically the most intense during the first day. However, if you have naturally sensitive teeth, you may notice the effects for longer than a week.

Here are some tips for managing sensitive teeth before, during, and after whitening treatment:

Before Whitening

The first step is to make sure you only buy sensitivity-reducing whitening products. These treatments typically contain lower concentrations of hydrogen peroxide and other ingredients specifically designed for sensitive teeth. 

Peroxide-free whitening products also do not cause sensitivity. But they are less effective. 

During Whitening

If you use an at-home whitening kit, only use a small amount of whitening gel to cover each tooth. Applying too much gel makes your teeth more sensitive. It will not result in quicker or more effective whitening. Using whitening gel in excess can also cause gum irritation.

Also, read the instructions carefully. Treatment duration and the amount of whitening gel needed vary from product to product. Overusing whitening gels increases the risk of sensitivity.

If you notice that the recommended treatment duration is too long, try shortening the sessions. This way you can see if the sensitivity is less severe.

After Whitening

Rinse your mouth and brush your teeth after each whitening session to remove any excess gel. Use lukewarm water and a soft-bristled toothbrush. 

Avoid consuming hot and cold drinks directly after whitening. These drinks can stimulate nerve endings and increase pain. Avoiding coffee and tea can also help your whitening results last longer.

You can also ask your dentist to recommend a prescription-strength gel or toothpaste to help reduce any sensitivity. Over-the-counter toothpaste that contains potassium nitrate can help with sensitivity. 

Summary

Choosing the best at-home whitening product depends on your needs, lifestyle, and budget. If you are looking for a quick and affordable solution, whitening strips or on-the-go whitening pens may be the best option. 

If you want a deeper whitening experience and have time for regular upkeep, an LED whitening kit is the perfect solution. While more expensive, these kits provide effective whitening and will give you a brighter smile quicker than over-the-counter products.

Professional teeth whitening is also available. These treatments are more effective than at-home LED whitening but cost $500 to $1,200 per treatment. However, the results can last for months. Contact your dentist’s office to determine if in-office whitening is for you.
