Is Teeth Bleaching the Same as Teeth Whitening?
The terms “teeth bleaching” and “teeth whitening” are often used interchangeably, but technically, they’re a little different. First, let’s talk about the types of stains that whitening can address. Extrinsic stains are stains on the surface of your teeth from food and drinks, smoking, and other outside causes. Intrinsic stains are stains on the internal structure of your teeth, typically from trauma, medications, or age.
Teeth whitening products, whether professional or over-the-counter, utilize peroxide-based bleaching chemicals, like hydrogen peroxide or carbamide peroxide. Known as bleaching agents, these compounds break down discoloration and stains on the tooth’s surface. Stronger formulations can also penetrate safely into the deeper layers of your tooth, whitening teeth from the inside and restoring a radiant smile.
However, the strength of the bleaching agent can vary quite a bit between at-home and in-office treatments, which impacts both their effectiveness and their potential for side effects. So yes, the bottom line is that all teeth bleaching is a form of whitening, even when the concentration of the bleaching agent varies.
What Are the Pros and Cons of Teeth Bleaching?
When deciding if teeth bleaching is right for you, it’s important to weigh the benefits and potential downsides.
Pros:
- Teeth bleaching offers noticeable results, lightening your teeth by several shades (sometimes in just one session).
- A whiter smile can boost your confidence, making you feel more attractive, youthful, and self-assured.
- In-office whitening treatments can produce gorgeous results in a short amount of time, while at-home treatments are easy to incorporate into your busy schedule.
Cons:
- Bleaching can cause temporary tooth sensitivity, making your teeth more sensitive to hot or cold temperatures.
- If the bleaching agent comes into contact with your gums, it can irritate or even burn them.
- Teeth whitening results aren’t permanent, especially if you continue to consume food and drinks that stain the surface of your teeth.
Comparing At-Home Teeth Bleaching to In-Office Teeth Bleaching
If you’ve decided to try bleaching your teeth, your next decision is how you want to do it: at home or at your dentist’s office.
At-Home Teeth Bleaching
Teeth whitening or bleaching kits are easy to purchase online or in-store. Common options include:
- Whitening strips
- Bleaching trays with gel
- LED light kits
- Whitening pens
At-home whitening options offer convenience and affordability, making them a popular choice. However, the downsides include slower results (due to a lower concentration of bleaching agents), less precise results, and a higher risk of side effects like tooth sensitivity.
In-Office Teeth Bleaching
Performed under the supervision of a dental professional, in-office teeth whitening options use higher concentrations of peroxide and LED lights or lasers to enhance your results.
In-office whitening options provide dramatic results in a short time and the ability to tailor the treatment to your specific needs and goals. Even though they use higher concentrations of bleaching agents, the procedure is performed by a professional, so there are more safety precautions and a reduced risk of gum irritation or tooth sensitivity. However, in-office whitening treatments are significantly more expensive and require time away from your day to attend an appointment.
Which Teeth Bleaching Option Is Best For Me?
Choosing the best teeth bleaching method depends on a few key factors, including your budget, the level of convenience you’re looking for, and how fast you want to see results. If budget and convenience are key, at-home kits might be the way to go. But if you want professional-level results with expert oversight, in-office bleaching is hard to beat.
Still unsure? Your best bet is to ask the skilled professionals at Dr. Chad Tomazin’s office. They will evaluate your oral health, recommend products, or offer in-office options tailored to your desired results.
Tips For Safely Bleaching Your Teeth
Whether you opt for in-office or at-home whitening, here are some tips to help you bleach your teeth safely and effectively:
Talk to Your Dentist First
Even if you’re going the at-home route, it’s smart to get your dentist’s input. They can let you know about any issues you may have (like cavities or gum disease) that might make bleaching unsafe.
Follow Bleaching Instructions to the Letter
This isn’t the time to skim the instructions. Too much bleach or leaving it on too long can lead to enamel damage and painful gum irritation.
Don’t Overdo It
When it comes to teeth bleaching, more isn’t better. Frequent bleaching can thin your enamel and make your teeth more sensitive.
Use a Toothpaste to Help Sensitivity
If you experience discomfort after teeth bleaching, switch to a toothpaste designed for sensitive teeth and avoid very hot or cold drinks for a few days.
Avoid Staining Foods and Drinks After Bleaching
Steer clear of coffee, tea, red wine, berries, and tomato-based sauces for at least 24–48 hours after your whitening session. Your teeth are more porous right after bleaching and can stain more easily.
Keep Up With Your Oral Hygiene
Whitening works best on clean, healthy teeth. Brush and floss regularly, and see your dentist for cleanings at least every six months.
