These are the quickest and most effective treatments for whitening.  During these treatments your dentist will put a protective gel on your gums and put an oral shield on your mouth to protect your gums and cheeks. They will then apply a bleaching agent to your teeth around your braces. Typically, these are made of varying concentrations of strong hydrogen peroxide. Most in-office treatments will use a special light to activate the bleaching solution, though other treatments are available using in-office bleaching trays. The bleaching solution needs to sit under the special light for at least an hour in most cases.  Sometimes the treatments will cause discomfort in the short-term. Bleaching gels can irritate gums and make teeth more sensitive. You may need more than one treatment for optimal results, depending on your dietary habits and the shade you want. These can be expensive and whitening treatments are not always covered by dental insurance. Since these treatments are done only once or twice, the bleaching solution may not soak into the enamel under your brackets.  For optimal results, wait to use this method until after your braces are taken off. However, if your brackets are on the back of your teeth this method is ideal as bleaching gel is only applied to the front of your teeth. This method might be a good option for you if your teeth have darkened since you got braces. Since it might not bleach the area under your brackets, it may be best to try other alternatives first. In-office whitening can be very expensive.  The average cost of in-office whitening procedures is $650.00. Compared to other very effective at-home treatments, this procedure costs much more. You will have to go to a dentist's office to get this treatment done. Not all dentists offer this service. The gel can have a very unpleasant taste and the cheek guards can be uncomfortable, as you will have to keep your mouth open for an hour or so. It may require more than one session to completely whiten your teeth. The best results come from changing the whitening gel every 40 minutes and repeating the session.

Q: If you find that you regularly irritate others, you might want to work on changing parts of your behavior. Start by thinking more positively. If your thoughts are positive, you are more likely to behave in an optimistic and approachable way. Every evening, think of three good things that happened today. Cultivating an attitude of gratitude can help you feel better and share these good feelings with others. An instructor can help you better identify the behaviors you need to work on and what you can do instead. You will be able to practice communicating well in a positive environment with other students who are trying to improve.  Look online for classes, seminars, or workshops in your area. You may be able to take a class at your school. Check with local therapists to see if they offer group workshops. A common reason that people get irritated is when they are treated rudely. Try to always use good manners so that you don’t upset someone. Don’t interrupt, always say please and thank you, and greet people in a friendly way. You can also be polite by respecting other people's’ personal space.  Be attentive to others. Show that you are listening by maintaining eye contact (or looking at them) and asking questions when appropriate. . Pay attention when they talk about how they feel, and take their emotions seriously. People deeply appreciate people who make them feel heard and understood. Making a habit of validating people's feelings can go a long way to helping them feel comfortable around you, and helping them enjoy spending time with you. It can be really irritating if someone is constantly talking about themselves. If you've realized that you are guilty of this, figure out some ways to correct the problem. For example, ask other people questions about themselves. If you're talking about how much you loved Breaking Bad take time to ask the other person what their favorite show is.   If you notice you've been talking about yourself a lot, pause and ask a question about the other person, such as "So how has your day been?" When someone is telling a story, try not to always jump in and say, "I had the same thing happen to me!" It's okay to empathize, but it's also okay to let other people steer the conversation. Notice whether the other person is asking questions. A person who is genuinely interested might prompt you to keep talking about yourself, in which case, keep doing so until the subject naturally changes. Maybe you irritated someone. That's okay, it  happens to everyone. Don’t beat yourself up for it. Occasionally being annoying doesn't make you a bad person. Instead, just make an effort to smooth things over by apologizing to the person you annoyed, if appropriate, and moving forward.
A: Practice positive thinking. Take a class on etiquette, communicating effectively, or speech. Be polite towards others. Validate people's feelings Talk less about yourself. Try not to be hard on yourself.
