The real cause of tooth discoloration
Our favorite at-home whitening solution
What Actually Causes Tooth Discoloration
Tooth discoloration is one of those things that can happen slowly enough that you don’t really notice it, until one day your smile looks a little less bright than it used to. And no, it’s not always because you’re doing something wrong.
Some stains happen on the outside of the teeth, which is called extrinsic discoloration. These are often caused by everyday things like coffee, tea, red wine, berries, cola, soy sauce, tobacco, or plaque buildup. Basically, many of life’s little pleasures are also quietly plotting against your enamel.
Other discoloration starts inside the tooth. This can happen because of aging, genetics, dental trauma, certain medications, past dental work, or health conditions. As enamel naturally thins over time, more of the yellowish dentin underneath can show through, which can make teeth look darker or less bright.
The good news is that many surface stains can be helped with consistent brushing, flossing, dental cleanings, rinsing with water after stain-causing drinks, and limiting tobacco. Whitening treatments may also help, depending on the type of discoloration. If one tooth suddenly changes color, or staining comes with pain, bleeding gums, bad breath, or visible holes, it’s worth checking in with a dentist.
Are Your Teeth Yellow?
Teeth whitening is one of those things many people think about but put off. It can feel expensive, inconvenient, or not worth the sensitivity that often comes with it. Professional, in-office treatments can cost up to $1,000, and still require time, appointments, and follow-ups.
Laughland offers a more flexible, at-home alternative. Instead of a one-size-fits-all formula, you can select the right whitening solution for your teeth, helping reduce sensitivity while still delivering noticeable results.
From there, everything is designed to be simple. The routine takes just 10 minutes a day and can be done at home, whenever it fits into your schedule. Each kit includes a whitening light with phone adaptors and three customized whitening pens, so you have everything you need to get started.
Laughland was formulated by a world-renowned dentist, and is trusted by over 200,000 customers for its natural ingredients and science-backed results. It’s one of the closest things you can get to professional whitening at home, with teeth up to seven shades whiter in as little as six days, guaranteed.
This month, you can get six at-home treatments for just $39 (60% off).
