One of the first things people notice about you is the quality of your smile, but if you’re feeling self-conscious about dental stains, you might worry about being judged for your appearance. If you’re overly afraid, you might even avoid spending time with others, which can detract from your daily quality of life.

There are many over-the-counter teeth whitening solutions available, but you might come to regret your decision if you try commercial-grade options rather than contacting your dentist. Continue reading to learn 3 excellent reasons to call your oral healthcare provider for teeth whitening, instead!

Reason #1: Protect Oral Health

Many people assume that their mouths must surely be healthy if they don’t see immediate issues, like damaged sections of enamel or dark, bleeding gums. However, it’s possible to have developed problems without knowing it, which can interfere with teeth whitening. For example, you might have gingivitis, the earliest form of gum disease, and accidentally trigger a painful reaction by applying chemicals to the already tender tissues. You might also have a hidden cavity between your teeth or behind your molars that could react negatively if whitening gel is applied over it.

Contacting your dentist for an appointment allows them to examine your mouth and address any potential concerns so that your smile is as healthy as it is beautiful following your elective service.

Reason #2: Achieve Consistent Results

Not only can you protect your dental condition by visiting your dentist for teeth whitening, but you can also achieve much more consistent coloration throughout your smile by pursuing professional treatment rather than over-the-counter options.

This is because store-bought kits often contain more diluted bleaches that are less effective, so they don’t produce the same quality outcomes as professional-strength gels. Not only that, but they rely on one-size-fits-all applicator trays that leave plenty of room for error, leading to overapplication or misuse of the product.

Reason #3: Avoid Potential Discomfort

Teeth whiteners work because the bleach they contain undergoes a chemical reaction in your mouth that breaks down the size and concentration of pigmented cells that have soaked into the microscopic pores of your enamel. Although effective, this treatment can also cause temporary sensitivity because it allows sensations to travel more easily through the lower layer of dentin into the roots inside.

However, if you apply teeth whitener to diseased, decayed, or damaged teeth and gums, such as if you have hidden cavities or early gum disease you are unaware of, then you might develop a painful reaction that requires an emergency visit to address.

As you can see, visiting your oral healthcare provider for teeth whitening offers several unique advantages that can help you build and maintain a beautiful, healthy smile!
