Your teeth play a significant role in your confidence, self-esteem, and appearance. Over time, teeth will naturally develop a yellowish-gray hue. However, eating and drinking heavily pigmented foods like coffee and red wine can cause premature discoloration. At-home teeth whitening kits claim to brighten smiles, but their results aren't always consistent or long-lasting. Below are several reasons not to invest your time in at-home teeth whitening products. 

Why Avoid Over-the-Counter Teeth Whitening Kits?

1. Uneven Whitening

OTC teeth whitening products come in various forms, such as brightening toothpaste, strips, pre-loaded brushes with bleach gel, and trays with whitening gel. Though these products may lift some discoloration from your teeth, they don't always produce even results. If you unevenly distribute the solution or gel on your teeth, they could develop bright patches that can make your teeth look worse. You could also experience uneven coloring if you need to brighten a few teeth to match the rest without resulting in an unsatisfactory outcome. 

2. Increased Tooth Sensitivity

Professional dental whitening uses a whitening gel to penetrate tooth enamel, the outermost layer of teeth, and lift surface stains. The gel is effective but acidic, so your dentist will cover gum tissues around your teeth to protect them. With at-home kits, there is little to no protection for your gums. Also, if you misuse the bleaching trays or strips, the acid from the products can destroy your enamel, leading to tooth sensitivity. The sensitivity can lead to pain or discomfort when your teeth are exposed to hot or cold temperatures.

3. Temporary Results

For a long-lasting bright smile, it's best to visit the dentist. Your dentist can lift up to eight shades from your teeth in a single appointment using professional-grade hydrogen peroxide gel and curing light. With the proper dental care, your brightened smile can last up to three years. 

However, if you choose at-home whitening kits to enhance your teeth, the results will not last as long. The effects could wear off within a few months, causing you to spend additional money to repeat the process.
