What Causes White Spots on Teeth After Whitening?

While most patients can all agree that visible white spots on the surface of your teeth are less than desirable in appearance, the excellent news is that, medically speaking, they aren’t considered a severe cause for concern. When it comes to what’s causing your teeth to develop white spots, there are a few underlying causes behind why this happens.

Read on to learn the causes of white spots on the teeth after whitening treatments, how you can treat them if they develop, and how to prevent them from coming back.

Experiencing Tooth Discoloration After Whitening Treatments

If your teeth have started to develop white spots, it’s not quite time to panic yet. There are several possible treatments for white spots on the teeth, and the suitability of these treatments may depend on the underlying cause of the white spots and why they have formed. Your teeth can become discolored by stains on the surface or by changes inside the tooth itself.

The three main types of tooth discoloration are:

1. Extrinsic. This occurs when the outer layer of the tooth (the enamel) is stained. Factors like drinking coffee, wine, or soda can also cause extrinsic stains.
2. Intrinsic. When the inner structure of the tooth (the dentin) darkens or develops a yellow tint. This type of discoloration appears from too much exposure to fluoride as a child, the use of tetracycline antibiotics during pregnancy or childhood, or from experiencing trauma to a tooth.
3. Age-Related Discoloration. The enamel that covers the teeth gets thinner as we age, and dentin naturally yellows over time.

Other Common Causes Of White Spots On Teeth

White patches on teeth after whitening is a common side effect of DIY whitening treatments. However, teeth whitening doesn’t cause white stains to develop. If your teeth already have stains on them, whitening treatments make the spots more visible. The most common causes of white spots on teeth include the following.

Poor Dental Hygiene

White spots on the teeth can also form due to an accumulation of harmful plaque bacteria. This results from poor oral hygiene and not correctly brushing and flossing regularly or long enough to ensure your mouth is clean. Insufficient oral hygiene or an inability to thoroughly remove plaque buildup causes the demineralization of the tooth, leaving a white spot behind.

Dental Fluorosis

One of the top contributing factors for patients developing white spots is dental fluorosis. Typically a harmless condition, patients typically get this when they are young if they consumed too much fluoride as a child. This condition only tends to develop before the teeth break through the gums and is a common cause of white spots on teeth.

Enamel Hypoplasia

Much like fluorosis, Hypoplasia is a condition that occurs when a patient’s teeth enamel does not form correctly as a child. Only occurring during childhood when a patient’s teeth are still in the development stage, enamel hypoplasia can increase the risk of a patient developing tooth decay, making you more susceptible to things like cavities and plaque buildup.

Braces or Other Orthodontic Treatments

Orthodontic white spot lesions appear as tiny white cavities that can negatively impact the smile you’ve worked so hard to achieve with orthodontic treatments such as braces. These white spots are caused by plaque buildup on the teeth from not thoroughly cleaning your teeth. Plaque buildup causes de-calcification, and a white cavity forms on the surface of the tooth.

Diet

The foods and beverages you enjoy can also have a role in white spots developing on the teeth. This can be caused by nutrition, genetics, excessive intake of too many acidic or sugary foods, and poor oral hygiene habits.

Talk To Your Dentist About How To Treat Stains and Discoloration

When it comes to whitening your teeth, it’s always a great idea to check with your dental professional before beginning any whitening regimen, especially if you are attempting to correct an issue such as white spots. Teeth whitening can help reduce the appearance of white spots and other stains, and depending on the severity of your white spots, an at-home whitening kit may be effective enough. If your white spots are more severe, a professional whitening treatment may be necessary to eliminate the white spots.
