Can my teeth become white again after turning yellow? Yes, there are a number of ways that you can help whiten teeth again after they have yellowed, from changing toothpaste and mouthwash to dental hygiene appointments.
Everyone's teeth get a little duller with age because the outer enamel layer thins out over time. Beneath this white enamel layer is dentin, which is yellowish. Additionally, this yellow dentin grows thicker as you age, making your teeth look more yellow or duller every year.
When the enamel is eroded so badly, in its thinnest form your inner layer can be seen, dentin. Dentin has a natural yellow color. So, if your enamel is transparent enough to show your dentin, your teeth look yellow even if you brush them every day.
Some of the most common causes of tooth discoloration include drinking beverages such as coffee, tea, and wine. These substances get into the enamel of your teeth and can cause long-term discoloration. Smoking: Smoking is one of the top causes of yellow or brown teeth, and stains from smoking can be stubborn.
As a person gets older, the white enamel on their teeth becomes worn. When this happens, the calcified tissue underneath starts to show through. This tissue is called dentin, and it has a yellowish color.
Water. Water is one of the drinks that whiten teeth. It not only keeps you hydrated, but it also helps prevent the formation of stains on your teeth. Swish some water in your mouth after you eat or drink pigment-rich foods or fluids to maintain a brighter, whiter smile.
Most tooth whiteners use one of two chemical agents: carbamide peroxide or hydrogen peroxide (the same stuff that will bleach your hair). When used in the mouth, carbamide peroxide breaks down into hydrogen peroxide and urea, with hydrogen peroxide being the active whitening ingredient.
Dairy products, such as cheese, yogurt and milk, contain lactic acid and the enamel-fortifying mineral calcium, which strengthen teeth while also whitening them. Chewing on cheese also prompts production of saliva, which washes away staining food particles.
Blueberries, blackberries, cherries, pomegranates, and other vibrant fruits can stain teeth. So can juices and pies made from them. Paler fruits, like white grapes and white cranberries, are less likely to cause stains. But they do have acid that can soften or weaken your enamel.
Purple is directly opposite yellow on the colour wheel and is therefore its complementary colour, so a water-soluble purple dye is applied to your teeth to cancel out any yellow undertones.
1. Their Permanent Teeth Are Starting to Come in. If your child is about 6-7 years old and their permanent teeth have started to erupt, you may notice that their permanent teeth look quite a bit more yellow than their baby teeth. Good news: this is normal.
Natural Enamel Thickness & Translucency
This yellowish hue shows through the enamel in almost everyone, but more so for those with naturally thinner or more translucent enamel. So your yellow teeth may be perfectly normal due to your genetics!
For about two to six weeks, you can use dentist-recommended whitening toothpaste and brush twice a day. You can use a certified whitening mouthwash which usually takes about three months to produce visible results. Whitening strips are the most compelling in-house treatments that last up to six months.
Teeth that have yellowed with age
As we age, the enamel becomes thinner due to wear and tear, revealing the underlying layer of tooth structure called dentin. Dentin is naturally yellowish and cannot be lightened with teeth whitening products.
Some people still have naturally whiter teeth than others. Maybe it's a result of good oral hygiene, maybe it's just good genetics, or maybe they're just young enough that their teeth haven't started yellowing yet. Unfortunately, all of our teeth tend to yellow and discolor with age.
Healthy teeth are naturally an off-white or slightly yellow hue, so don't be alarmed if they're not blindingly white. But if you would like to achieve a brighter smile, always contact your dentist for treatment – it's the safest option for your grin!
