In this guide, we’ll walk you through everything you need to know about professional teeth whitening. You’ll learn about what happens during the procedure and how long results may last.
By the end, you’ll have a clear idea of your options and what to expect. That way, you can decide if professional teeth whitening is right for you!
What Is Professional Teeth Whitening?
Professional teeth whitening brightens your smile by removing stains and lightening your teeth. Unlike store-bought products, this teeth whitening is done by a dentist who uses specific materials.
Your dentist will customise the treatment to suit your needs. Some people prefer a natural-looking brightness, while others want a more dramatic change. No matter your goal, professional teeth whitening can help enhance your smile significantly.
How Does Professional Teeth Whitening Work?
Professional teeth whitening uses a gel that contains hydrogen peroxide or carbamide peroxide. These ingredients break down the stain molecules on your teeth. That way, they can lift the discolouration and reveal a whiter smile.
Your dentist will add the whitening gel to your teeth with caution and precision. The entire process is designed to be comfortable, helping you achieve a brighter smile in a controlled environment.
Benefits Of Professional Teeth Whitening
Choosing professional teeth whitening instead of home treatments has many advantages. Here are some of the key benefits:
More Effective Results
Professional whitening treatments work faster and provide more noticeable results than at-home options. The whitening agent used in these treatments is stronger, helping remove deep stains and discolouration more effectively.
Customised Treatment
Everyone’s teeth are different, and a one-size-fits-all approach may not work for them. A dental professional will check your teeth, gums, and oral health to create a whitening treatment that suits your needs.
Whether you want a subtle change or a brighter smile, your dentist will tailor the treatment for the best outcome.
Supervised Care
Teeth whitening done by a professional is more precise than over-the-counter whitening products. Your dentist will take steps to safeguard your gums and tooth enamel, reducing the risk of side effects.
The procedure is performed under expert care, ensuring a comfortable and pleasant experience.
Long-Lasting Results
Sticking to good oral hygiene practices and following your dentist’s aftercare advice can help make your results last longer.
What To Expect During Professional Teeth Whitening
If you’ve decided to have professional teeth whitening, you might be wondering what happens during the procedure. Here’s what you can expect:
Consultation
Before starting, your dentist will check your teeth and gums to make sure they are healthy. They will talk to you about your whitening goals and recommend the best treatment for you. If you have any concerns, this is a great time to ask questions.
Preparation
To get the best results, your dentist will clean your teeth first. This helps remove plaque and surface stains so the whitening gel can work more effectively. Your gums may also be protected with a specific barrier to prevent irritation.
Whitening Process
Once your teeth are ready, your dentist will carefully apply a teeth-whitening gel. The gel contains bleaching agents which help break down stains. The dentist will contain the gel using whitening trays to prevent saliva from diluting it.
Your teeth are left for around 30 minutes before being washed away by the dentist. Once this step is over, your new smile will be up to 8 shades whiter.
Post-Treatment Care
After the procedure, your dentist will give you aftercare instructions to help maintain your results. They will tell you to avoid or limit foods and drinks that stain your teeth, practise oral hygiene, and attend dental check-ups.
How Long Does Professional Teeth Whitening Last?
One of the most common questions about professional teeth whitening is how long it will last. Professional teeth whitening can last anywhere from 2 to 3 years on average.
Some people may notice their brighter smile lasting even longer with proper care. Yet, others might see stains return sooner if they have poor oral hygiene.
Factors That Affect Longevity Of Teeth Whitening
There are several things that can affect how long your teeth stay white, whether before or after a professional teeth whitening treatment:
Oral Hygiene Habits
Taking care of your teeth is necessary for keeping them white. Brushing your teeth and flossing daily helps prevent stains from forming. Also, regular visits for cleanings can help maintain your whiter smile.
Diet Choices
Some dietary choices, including coffee, tea, red wine, and dark berries, can cause stains over time. If you limit these or rinse your mouth with water after consuming them, your teeth will stay whiter for longer.
Smoking And Tobacco Use
Smoking and using tobacco products can make your teeth turn yellow faster and reduce the effects of whitening. If you want to keep your teeth looking bright, try to avoid smoking and using tobacco products.
Age
As you get older, the enamel on your teeth wears down naturally. This can cause the yellowish dentin inside your teeth to show through, making your teeth look less white.
Medications
Some medications can make your teeth discoloured. If you take any medications, talk to your dentist about how they might affect your whitening results.
How To Maintain Your Whiter Smile
To extend the results of your whitening, consider the following tips:
Brush your teeth at least twice a day with a whitening toothpaste.
Floss daily to remove plaque and prevent staining.
Use a straw when drinking dark beverages to reduce contact with your teeth.
Schedule regular dental visits for professional cleanings.
Follow any aftercare advice given by your dentist.
By following good oral hygiene habits and making mindful choices, you can enjoy your brighter smile for as long as possible!
Possible Side Effects Of Professional Teeth Whitening
Professional teeth whitening is an accurate way to brighten your smile. Yet, like any dental treatment, there may be some temporary side effects. It’s important to be aware of these so you know what to expect and how to manage them.
Tooth Sensitivity
One of the most common side effects is tooth sensitivity. After the whitening treatment, you may notice that your teeth react more to hot or cold foods and drinks.
This happens because the whitening gel temporarily weakens the enamel, exposing the inner layers of your teeth. The sensitivity should go away within a few days.
To manage sensitivity:
Use a toothpaste designed for sensitive teeth.
Avoid very hot or cold foods for a few days.
Brush gently with a soft-bristled toothbrush.
Gum Irritation
Some people experience mild gum irritation after the procedure. This can happen if the whitening gel touches the gums. The irritation is usually temporary and should improve within a few hours to a day.
To reduce gum irritation:
Avoid spicy or acidic foods that may aggravate the gums.
Rinse your mouth with lukewarm salt water to soothe any irritation.
If irritation persists, speak with your dentist for further advice.
Temporary Tooth Discolouration
Sometimes, teeth may appear slightly blotchy or unevenly coloured right after the procedure. This is normal and happens as the whitening gel continues to work. The colour should even out within a few days, leaving you with a brighter, more uniform smile.
Frequently Asked Questions
How long does the teeth whitening procedure take?
The in-office teeth whitening procedure usually takes about one hour. Other teeth whitening methods, like at-home teeth whitening kits, may take several days or weeks to give you the results you want.
Will professional teeth whitening work on crowns or veneers?
No, professional teeth whitening will not change the colour of crowns, veneers, or other dental restorations. If you have these, talk to your dentist about other treatment options.
Can professional teeth whitening remove all stains?
Professional teeth whitening works best on surface stains from food, drinks, or smoking. Some deep stains from medicine or tooth injuries may not come out. Your dentist can help with other options if needed.
How often should I get professional teeth whitening?
Most dentists suggest waiting six months to a year between whitening treatments. This helps avoid tooth sensitivity or damage. Brushing well and avoiding staining foods can help keep your results for longer.
How much does teeth whitening cost?
The cost of teeth whitening is based on the treatment you choose and where you go. In-chair teeth whitening usually costs more than store-bought products. Your dentist can give you a clear idea of the cost and any payment options that might be available.
