Q: When your enamel breaks down there are many ways in which your teeth physically change. From the color to the shape, the loss of enamel can cause your teeth to look drastically different. Dentin is the yellowish layer of your tooth located under your enamel. As the enamel wears down and the dentin gets thinner and a thinner layer of enamel covers the dentin, it becomes more transparent and your teeth will appear more yellow. How yellow your teeth are is a good indication of how thin your enamel is; the less enamel you have, the more yellow your teeth will be. If you're uncertain as to whether your teeth are yellow from stains or due to enamel loss, try having them whitened. Artificial stains will come off. Another way in which your teeth physically change when enamel loss occurs is a change in shape. Your teeth may appear to be rounded and short. When you lose enamel your teeth may take on a rounded shape and can also cause your teeth to look shorter than normal. If you have a tooth filling, you may notice that your tooth seems to have shrunk around the filling. This shrinkage is caused by the loss of tooth enamel. Teeth that have lost a good deal of enamel may develop fractures or chips. Even if your teeth haven't developed fractures yet, you should see a doctor as soon as you notice that your teeth are looking brittle and thin. This is a sign that they might fracture soon. When enamel wears down the dentin layer underneath is revealed. Not only does this make your teeth yellow, it also makes them very sensitive to pain. This sensitivity may arise when you eat hot or cold foods and occasionally sweet foods, or when you inhale cool air. In severe enamel and dentin decay, the pulp, which is the innermost part of the tooth, could also become damaged, leading to a lesion called pulpitis. If this is the case, you will experience severe pain when you eat. When enamel and dentin begin to thin your teeth may appear shorter and you may find it more difficult to chew. The chewing surfaces of your teeth become flattened, which causes you to bite and chew your food with difficulty. Aside from it being more difficult to chew, you might also experience pain when you take a bite of food. Enamel loss makes your teeth brittle and prone to cavities. This is because enamel protects your teeth from plaque and debris buildup. When the enamel isn't there, plaque and debris buildup can result in cavities. The cavities on the surface of the tooth can enter into the deeper parts of the tooth through the opening that missing enamel has left unprotected. This can cause extreme pain and in some cases, infection due to bacteria that has an easier access through the porous structure of dentin.
A: Watch for discoloration. Look for a change in shape. Check for cracks or chips. Pay attention to any tooth sensitivity that develops. Pay attention to your biting force. Check your teeth for cavities.

Q: There's no point doing this if the school specifically forbids it. If you're at a sugar-free school or a school focused on healthy eating and no candies, you'll likely get yourself into trouble with the authorities if you haven't told them and get found out. Realize that parents who don't want their children eating sugar may make trouble in such a case. What kind of candy do people at your school want? Does anybody else sell candy? You need to know everything you can in order to maximize profit. The most popular candy tends to be candy bars but it may depend on where you are and what the current fad is. Realizing this is your first step, because you will most likely be let down. Think small, but by all means think profit!!!
A: Find out whether or not it's okay to sell candy at your school. Do some market research. Realize that you won't become rich overnight, and maybe not at all.

Q: Don't initiate any contact with your ex, including phone calls, texts, emails, messages on social media, and in-person conversations. If he tries to initiate contact with you, don't respond. Depending on the situation, you may want to respond to a text or email by simply telling your ex that you are not interested in talking to him. If he is being completely unreasonable, don't bother responding. If you are getting threatening messages from your ex or he is stalking you, report the behavior to the police immediately. You may be able to get a restraining order to keep him from contacting you or coming near you. If your ex-boyfriend will not stop calling, texting, or emailing you, you can block his number and email address. If he is very persistent and starts calling you from other people's phones or emailing you from different addresses, you might want to consider changing your phone number and/or email address. Most social media sites allow multiple options for blocking or ignoring a person. If you want to prevent your ex-boyfriend from viewing your profile and you want him to get the message that you don't want any contact with him, block him. If you don't want to take it to that extreme, but you also don't want to see any updates from your ex, ignore or unfollow him. If possible, avoid places where you know you are likely to run into your ex. If this is not possible, just keep walking when you see him instead of stopping to talk. If you share mutual friends, have classes together, or work together, you might have no choice but to spend some time in the same room with your ex. It might be hard at first, but do your best to interact with everyone else in the room normally, and avoid talking to your ex as much as possible. Don't go overboard by literally pretending not to see him. This will probably make him think that you're uncomfortable being around him, which is not what you want. Instead, address him as you would a stranger. Keep your interactions brief and avoid body language that suggests intimacy, like direct eye contact. If you're with a group of people, make an effort to talk to other people in the group instead of to your ex-boyfriend. If your ex starts talking to you, respond politely, but very briefly, so he will know you're not interested in talking. For example, if he says, "That math test was really hard. How do you think you did," just say, "Fine," and show no interest in continuing the conversation. If your ex-boyfriend tries to use other people to give you messages, respond according to the situation. If the messenger is your friend, just tell him that you're not interested in hearing what your ex has to say and you hope that he won't let that get in the way of your friendship. If the messenger is not your friend and has been sent by your ex to say something mean to you, just ignore him. If you're like most people, your boyfriend was probably the first person you went to for consolation when something bad happened to you, and also the first person you told when something exciting happened. This can make it very hard to let go of your ex because you may still feel like contacting him in these situations. Instead, try turning to a friend, a sibling, or a parent. It might be tempting to replace your ex with a new boyfriend, but don't do this unless you're really ready to commit yourself to a new relationship. If you do feel ready, then go ahead and date new people. It will be much easier to ignore your ex-boyfriend if you really are occupied with other things. Start doing more things with your friends, join a club, or take up a new hobby to get your mind off your ex and make ignoring him completely natural. If you and your ex-boyfriend are in the same social circles, it will help if he sees you looking happy and enjoying life without him. This will make him feel like none of the mean things he's been doing are having any effect on you.
A:
Avoid contact. Don't talk directly to him. Find new attachment figures. Stay busy.
