Your smile portrays confidence, but if your teeth have become yellow or discolored over time, you may not have the confidence to let others see it. Teeth whitening has become a popular treatment for millions of people looking for ways to brighten their smile, and bring back the confidence to show those pearly whites.
Our teeth are meant to be white, but over time our habits can cause discoloration, yellowing, or worse. Some of the most common reasons teeth become discolored-many of which are preventable-include:
At a young age, our teeth are healthy and white but over time the enamel coating the tooth is slowly worn down, causing our teeth to become stained and yellow which is why teeth whitening is becoming increasingly popular today. There are a few methods for whitening – they include at home and in office. With in-office treatments you will see faster results, receive the safest treatments for bleaching the teeth and yield the whitest smile. So don’t settle for teeth that have become stained from years of coffee drinking, tobacco use or just ageing. Ask your dentist about whitening options that maybe right for you.
Teeth whitening has become one of the most popular dental treatments offered. At Esquire Dental Centres we have a wide variety of bleaching and whitening options, including Zoom Whitening, in-office, and take-home bleaching kits. Our highly qualified team of dental experts can transform your smile from dull to bright in our clean, comfortable, and state-of-the-art dental offices. If you choose in-office whitening, the procedure can be completed in about an hour. With at-home whitening, you will see gradual improvement every day until desired results are achieved.
The cost of teeth whitening in Ontario can range from $200 to $650, depending on the type of treatment. Professional in-office whitening tends to be on the higher end, offering faster and more noticeable results. Custom take-home kits from a dentist typically cost less than in-office treatments. Over-the-counter products are cheaper but may provide less effective results. It’s good to consult your dentist to determine which option suits your needs and budget.
Teeth whitening is considered a cosmetic procedure and is typically not covered by dental insurance in Canada. Most insurance providers focus on treatments necessary for maintaining oral health, such as cleanings, fillings, or crowns. However, it’s a good idea to check with your specific insurance provider to see if they offer partial coverage or discounts through a dental plan. If whitening is a priority, ask your dentist about affordable options or payment plans.
Eligibility for teeth whitening depends on your oral health and the cause of discoloration. Individuals with healthy teeth and gums typically qualify for treatment. However, those with tooth decay, gum disease, or dental restorations (like crowns or veneers) may not see effective results. Pregnant or breastfeeding women are generally advised to wait. Your dentist will evaluate your oral health and recommend the most suitable whitening approach for your specific needs.
In-office whitening treatments, such as Zoom, use higher concentrations of whitening agents, typically hydrogen peroxide, to achieve rapid results. These gels are activated with light or heat to accelerate the whitening process, delivering noticeable changes within an hour. Take-home kits, on the other hand, use lower-concentration gels, often with carbamide peroxide, which breaks down into hydrogen peroxide more gradually. This slower process is safer for at-home use but requires daily application over a few weeks for comparable results. Because of the differences in gel strength and application time, in-office treatments are ideal for those looking for immediate results, while take-home kits allow for a more gradual, flexible whitening experience. Discuss your lifestyle and goals with your dentist to choose the ideal option for you.
Teeth whitening can cause temporary sensitivity due to the active ingredients opening up the microscopic tubules in your teeth, exposing them to temperature changes. This effect is usually short-term and subsides within days after treatment. If you already have sensitive teeth, your dentist can adjust the treatment by using a lower-concentration gel, applying a desensitizing gel, or recommending shorter whitening sessions. Take-home kits also offer the option to space out treatments, reducing sensitivity risk. With proper guidance, most patients do not experience long-term sensitivity from whitening. However, sharing any history of tooth sensitivity with your dentist can help ensure a more comfortable whitening experience tailored to your needs.
Whitening agents are designed to lighten natural tooth enamel but won’t affect the colour of restorations like crowns, veneers, or fillings. This difference means that after whitening, restorations may appear darker or mismatched against your newly brightened teeth. If you plan to whiten, it’s helpful to do so before getting restorations placed so they can be matched to the desired shade. If you already have visible restorations, your dentist can offer options to replace or update them after whitening for a consistent appearance. Be sure to discuss any restorations with your dentist before whitening to set realistic expectations and maintain a balanced, uniform smile.
The results of teeth whitening can last from six months to two years, depending on your lifestyle and oral hygiene habits. Smoking, drinking coffee, tea, or red wine can cause stains to return more quickly. Maintaining good oral care, including regular brushing, flossing, and professional cleanings, helps prolong the effects. Your dentist may also recommend touch-up treatments with whitening trays to maintain your bright smile over time.
Yes, teeth whitening is generally safe when performed by a dental professional or when using dentist-recommended products. Professional treatments are designed to minimize sensitivity and protect your tooth enamel. However, excessive or improper use of over-the-counter whitening products may cause gum irritation or enamel damage. Always follow your dentist’s recommendations and avoid DIY methods that could harm your teeth or gums.
Teeth whitening is usually painless, but some individuals may experience temporary tooth sensitivity or gum irritation during or after treatment. This sensitivity is typically mild and subsides within a few days. Using desensitizing toothpaste and following your dentist’s aftercare instructions can help manage discomfort. Professional treatments are carefully monitored to minimize these side effects. If sensitivity persists, consult your dentist for further guidance.
Teeth whitening is not permanent. Over time, teeth can become discolored again due to aging, dietary habits, and lifestyle choices like smoking. Maintaining good oral hygiene and avoiding stain-causing foods and beverages can help prolong the results. Your dentist may recommend periodic touch-up treatments to keep your bright smile. Professional whitening treatments tend to provide longer-lasting results compared to over-the-counter options.
Results from in-office whitening treatments can last anywhere from several months to a couple of years, depending on lifestyle and diet. Habits like drinking coffee, tea, red wine, and smoking can cause stains to reappear more quickly. Practicing good oral hygiene and avoiding stain-causing foods and drinks will help maintain your results longer. Many patients opt for touch-up whitening treatments every 6-12 months to keep their smile bright. Some dentists also offer take-home kits to help patients maintain results gradually. Regular dental cleanings are another effective way to keep your teeth stain-free. Talk to your dentist about the ideal maintenance plan based on your lifestyle and whitening goals.
Yes, certain oral health conditions can make whitening less safe or effective. For example, patients with active gum disease, exposed roots, or untreated cavities are advised to avoid whitening until these issues are resolved. Whitening agents can exacerbate sensitivity or irritation in compromised areas. Likewise, patients with enamel erosion or thin enamel may find whitening uncomfortable, as the process can increase sensitivity in already delicate areas. It’s essential to undergo a dental exam before whitening to ensure your teeth and gums are healthy enough for treatment. Your dentist can provide recommendations and, if needed, help address any issues beforehand to ensure safe, comfortable whitening results.
