One of the first things others notice about you is the quality of your smile, and if yours is tinted more brown or yellow than pearly white, you’re less likely to make a good impression. You probably already know that various commercial products can potentially help lighten your teeth, but you might avoid them if you’re scared of developing sensitivity.

Fortunately, there are several proactive things you can do to avoid this potential discomfort. Continue reading to learn 3 ways to prevent tenderness after having your teeth whitened!

Tip #1: Start With Your Dentist

Although many over-the-counter options claim to be able to remove stubborn dental stains, these methods tend to contain diluted bleaching agents that are less effective. Plenty of people have developed aches by overapplying cheaper bleaches in an attempt to see the desired changes only to be disappointed by the lack of results.

Meanwhile, your dentist offers professional-grade solutions that are designed to achieve optimal outcomes while mitigating potential sensitivity. Whether you opt for an in-office visit for instant results or prefer customized take-home kits with custom-fitted trays, they’ll take the time to examine your mouth first to ensure that no pre-existing problems, like cavities or gum disease, interfere painfully with your results.  

Tip #2: Use the Right Products

Even with professional whitening services, there’s a possibility you might develop temporary sensitivity because the bleach placed on your enamel opens the pores. This exposes the microscopic tubules that lead through the lower layers of dentin, closer to the tender roots of your teeth.

You can reduce this short-term discomfort by remineralizing your enamel with a special toothpaste or mouthwash containing fluoride. You may also consider purchasing desensitizing pastes or numbing gels that reduce sensation in your enamel and gums. If you’re using over-the-counter whitening products, opt for those with lower peroxide concentrations.

Tip #3: Watch What You Eat

Once the pores of your teeth have expanded, you’re likely to experience tingling or sensation when consuming anything too hot or cold. For example, you might struggle to enjoy a hot cup of coffee or bite into ice cream until a few days have passed.

Thankfully, you can avoid any unpleasant feelings by eating milder foods that aren’t prepared at extremely high or low temperatures (i.e., boiling or frozen). You can also limit your consumption of overly acidic or sugary foods that wear down your enamel and attract unhealthy bacteria that contribute to cavities and gum disease.

Teeth whitening shouldn’t cause persistent or lasting aches. If you experience pain that worsens after several days, contact your provider so they can identify and treat the underlying cause.
