Having your teeth professionally whitened can boost your confidence levels, make you look more youthful, and improve your overall appearance. The majority of people would prefer to have whiter teeth, which is why teeth whitening tubes of toothpaste stock the shelves, and teeth whitening kits are widely available. Teeth whitening is a safe procedure when you visit a dentist to have the process completed professionally. While home kits are often safe, they can lead to complications including swelling of the gums, lips, and tongues. Teeth whitening can result in some sensitivity, whether it was carried out by a professional or not. You may notice that you are sensitive to fluids of all temperatures and cold air. However, this should resolve within 48 hours. The results are noticeable immediately, but it can take up to two weeks to see the full effect. The length of the teeth whitening process will depend on the patient, but the entire procedure generally takes around 90 minutes. It will depend on how much lightening your teeth need and for some, it will take several sessions to achieve the desired shade. Even if yours is a quick procedure, you should speak to your dentist about the next treatment because it’s important to maintain results.
