1. Overusing Whitening Strips
Whitening strips are an affordable, convenient way to get your teeth a bit whiter at home. Although they can effectively whiten your teeth, whitening strips can start to damage your teeth if you wear them too long and too often. Wearing whitening strips for too long increases your risk of tooth sensitivity. Ensure you follow the manufacturer's instructions and talk to your dentist if you are still experiencing discomfort or painful tooth sensitivity.
2. Using Baking Soda
You may have heard that baking soda can clean your teeth and remove surface stains, but baking soda isn't the best or most effective whitening option. If you use household baking soda, its abrasiveness can weaken parts of your enamel, increasing sensitivity. It's generally safer to use a whitening toothpaste than it is to brush with baking soda.
3. Using Lemon Juice or Apple Cider Vinegar
Unfortunately, using lemon juice, apple cider vinegar or another acidic liquid to whiten your teeth can cause enamel erosion. Keep in mind the NHS says that citrus fruits, such as lemons, are one of the foods that can damage teeth.
4. Using Ill-Fitting Whitening Trays
One-size-fits-all teeth whitening trays sold in shops can lead to some problems. The whitening gel may leak if the tray doesn't fit your mouth, potentially irritating your gums. Also, if the whitening ingredients leak out of the tray, you may not see results! These are the reasons why getting a customised tray from your dentist is often more effective, even if it is more expensive than the over-the-counter whitening trays.
5. Using Any Product Not Designed for Teeth
You may see even more recommendations for at-home teeth whitening, using household products like hydrogen peroxide or even bleach. However, these products were not created for oral care and can lead to damage or worse. Seek out oral care products from oral care experts! Check with your dentist and remember that anyone who administers teeth whitening treatments must legally be registered with the General Dental Council.
Remember these five common mistakes as you search and speak with your dental hygienist, dental therapist and dentist about whitening options. Your dental professional can recommend the best whitening treatment or product for your needs to ensure you don't accidentally cause damage or tooth sensitivity. There are safe ways to do at-home teeth whitening, especially when you ask a professional.
