Teeth whitening is a popular cosmetic dental procedure. Many people want a brighter smile. Dentists use professional teeth whitening gels to achieve the best results. These gels are different from over-the-counter products. They are stronger and more effective. In this article, we will discuss the types of whitening gels dentists use, how they work, and why they are better than store-bought options.
Types of Teeth Whitening Gels Dentists Use
Dentists use different types of whitening gels. The most common ones are hydrogen peroxide and carbamide peroxide. These gels come in various strengths. The strength depends on the patient’s needs.
Hydrogen Peroxide Gels
Hydrogen peroxide is a strong bleaching agent. Dentists use it in concentrations between 15% and 40%. Higher concentrations work faster but can cause sensitivity. Dentists control the application to avoid damage to gums and teeth.
Carbamide Peroxide Gels
Carbamide peroxide is another common whitening gel. It breaks down into hydrogen peroxide and urea. Dentists use it in concentrations from 10% to 35%. It works slower than hydrogen peroxide but is gentler on teeth.
In-Office Whitening Gels
Dentists use special gels for in-office treatments. These gels are very strong. They often contain hydrogen peroxide in high concentrations. The dentist applies the gel and may use a light or laser to speed up the process. Results are visible in one session.
Take-Home Whitening Gels
Dentists also provide custom take-home whitening kits. These gels are weaker than in-office gels. They usually contain carbamide peroxide. The patient wears custom trays for a few hours each day or overnight. Results take a few days to weeks.
How Dentist-Used Whitening Gels Work
Whitening gels break down stains on teeth. The active ingredient (hydrogen peroxide or carbamide peroxide) penetrates the enamel. It reacts with the stain molecules, breaking them into smaller pieces. This makes the teeth look whiter.
In-Office Whitening Process
The dentist cleans the teeth to remove plaque.
A protective barrier is applied to the gums to prevent irritation.
The whitening gel is applied to the teeth.
A special light or laser may be used to activate the gel.
The gel is left on for 15-30 minutes, then rinsed off.
The process may be repeated for better results.
Take-Home Whitening Process
The dentist takes impressions of the teeth to make custom trays.
The patient fills the trays with whitening gel.
The trays are worn for a few hours or overnight.
Treatment lasts from a few days to a few weeks.
Why Dentist-Used Gels Are Better Than Store-Bought Products
Dentist-used whitening gels are more effective than over-the-counter products. Here’s why:
Higher Concentration of Active Ingredients
Store-bought whitening gels have low concentrations of hydrogen peroxide (3%-10%). Dentist-used gels have much higher concentrations (up to 40%). This means faster and better results.
Customized Treatment
Dentists adjust the treatment based on the patient’s needs. They consider tooth sensitivity, gum health, and desired results. Store-bought products are one-size-fits-all.
Better Safety
Dentists protect gums and soft tissues during whitening. Over-the-counter products can cause gum irritation if not used correctly.
Longer-Lasting Results
Professional whitening lasts longer than store-bought treatments. Dentists also provide maintenance tips to keep teeth white.
Possible Side Effects of Teeth Whitening Gels
Teeth whitening is safe but can have side effects. The most common ones are:
Tooth Sensitivity
Some people experience temporary sensitivity after whitening. This happens because the gel opens tiny pores in the enamel. Sensitivity usually goes away in a few days.
Gum Irritation
If the gel touches the gums, it can cause irritation. Dentists use barriers to prevent this. Over-the-counter users may not have this protection.
Uneven Whitening
Teeth with restorations (fillings, crowns) do not whiten. This can lead to uneven color. Dentists advise patients before treatment.
How to Maintain Whitened Teeth
After whitening, it’s important to maintain results. Here are some tips:
Avoid Staining Foods and Drinks
Coffee, tea, red wine, and dark sodas can stain teeth. Smoking also causes discoloration. Limit these to keep teeth white.
Practice Good Oral Hygiene
Brush twice a day and floss daily. Use a whitening toothpaste to remove surface stains.
Touch-Up Treatments
Dentists may recommend touch-up treatments. These can be done at home with custom trays.
Conclusion
Teeth whitening gels used by dentists are the most effective way to get a brighter smile. They contain higher concentrations of bleaching agents and provide faster results. Dentists ensure the treatment is safe and customized for each patient. While over-the-counter products are cheaper, they are not as strong or long-lasting. If you want professional-grade whitening, visit a dentist. They will help you achieve the best results with minimal side effects. A white smile boosts confidence and improves appearance. With proper care, the results can last for months or even years.
