Dental cleaning: preparing for in-office teeth whitening
What do I need to do before in-office teeth whitening?Getting your teeth whitened in your dentist’s office can yield quick results.So, to score a gleaming smile it may be well worth its while to prepare yourself for the procedure.Here is what you need to do. Before teeth bleaching at a dental office you:
- Should brush your teeth.
- Consider using lip balm before to avoid dry or sore lips.
- Should also get your teeth cleaned.
In-office dental bleaching
How does in-office teeth whitening work?Now, not all procedures are created equal. ?Yes, there are some variations amongst different procedures.But do not worry. We describe the main steps below, and we will explain the differences in the next sections.All in-office teeth whitening procedures follow a somewhat standard routine. A trained dentist will:
- Take a shade measurement of your teeth before the procedure begins.
- Shade measurement aims to compare your existing tooth color to a shade with a stylized chart.
- This provides a benchmark to gauge improvement after teeth whitening.
- Once this (benchmark) has been determined, the whitening process will take place.
- Polish your teeth using pumice.
- Place a cheek retractor to expose all the teeth that are visible when you smile.
- Cover your eyes, gums, and lips, to protect them from the bleaching gel.
- A hardening resin or a liquid rubber dam is used and painted over the gums.
- The tips of the gums between the teeth will also be protected from the bleaching agents.
- Finally, only your teeth will be exposed. This process may take up to 10 minutes.
- Apply a special whitening gel to your teeth.
- Remove the previous layer during each session.
- Make you rinse your mouth with a lot of water, and polish your teeth with pumice again (if necessary).
- Assess the degree of teeth whitening to gauge whether the procedure should be repeated or not.
- Apply more whitening gel if necessary.
- Remove your cheek retractors so that you can rinse your mouth.
- Take your final teeth shade.
- “heat and light application may initially increase whitening due to greater dehydration”;
- “this reverses with time” and is also referred to as rebound;
- the final color will be visible 2-6 weeks after the procedure.1
How many visits and in-office teeth whitening procedures do you need?You will be happy to hear that …Your dentist will usually not have to set up a regime with multiple visits to get your healthy grin back.The average is one visit.Albeit, depending on the results, or your desired outcome, another session may be necessary.Your dentist may also suggest continuing the treatment with home whitening trays.So, tray delivery may help complete the whitening process.Albeit, depending on the individual case, the exact approach could vary.We previously mentioned the use of light sources.Let’s investigate a little.
How many light sources can be used during accelerated or LED in-office teeth whitening?Your best guess? One, two or more sources?Actually, the correct answer is three.The following sources of light are the most frequently used:
- plasma arc,
- and halogen.
Is laser light, used for in-office teeth whitening, effective?The short answer is that there is not a lot of data about the efficacy of laser bleaching.Also, the data is difficult to compare because of the differences:hydrogen peroxide showed improved whitening.Bear in mind though that:
- “Most often, comparable results were found irrespective of light exposure.”3
- “There is no evidence that light activation (power bleaching with high-intensity light) with high concentrated hydrogen peroxide bleaching gels results in more effective bleaching with a longer lasting effect.”4
Is in-office teeth whitening painful or uncomfortable?Fear not, my young Padawans. ?The procedure is neither painful nor uncomfortable.To the point that most patients usually listen to music, watch a DVD or doze off, during the entire procedure.Yes, you understood right, most patients are very relaxed.
What are the advantages and disadvantages of in-office teeth whitening?If you want fast results, in-office procedures are the way forward.Unlike home bleaching techniques, results are quick and visible after a one-hour session.Home whitening techniques instead are slower and are intended to be used over a period of 2-4 weeks.5However, you will benefit from staying in the comfort of your own home.Also, they are less expensive.
