Glad to hear you are getting back on track with your oral care and improving your smile. Without pictures to see the severity of the discolorations, its difficult to make the appropriate recommendations. It is wise to wait till after ortho is done before doing crowns (as long as you discuss expectations of your final look with them). Bleaching your teeth with a product called KOR can have some dramatic effects on the color of your teeth, however, it will not change the color of your fillings. My suggestion would be to consult with a dentist, explain your wishes and expectations so they can guide you towards the treatment that will produce the best results till crown work can be done. Best of luck to you.
Wow, it sounds like you've been through a lot of dentistry to fix your smile. Considering the issues you are wanting to address, veneers can fix the enamel chipping. However, veneers will not address the labial cant or "bucked" appearance of the top teeth. It may even accentuate your current profile. Sometimes, we can bring the incisal edges back a little bit based on how the tooth preparation is done, however, it may not be enough to significantly address your concerns. My suggestion is to seek out a dentist who you can have good conversation with to discuss your options, limitations of certain treatments and a clarification of expectations so that you end up with a smile you are going to be happy with. Best of luck to you.
Sorry to hear you are having discomfort with your temporary. It can be an issue with your occlusion on the temporary crown. If the opposing tooth is hitting heavily on the temporary, it can "bruise" the ligaments that hold the tooth into the bone, set up inflammation and be the source of pain when applying pressure. The tooth can also become hypersensitive to cold because the temporary margin may not be covering all the tooth structure, inflammation in the gums secondary to a rough temp can also allow cold liquids to contact that more sensitive part of the tooth. Let your dentist know what symptoms you are experiencing and they may have you come back into the office, potentially make some adjustments to your temporary and your tooth will be feeling much better. Hope this helps.
Its great you're getting to "test drive" them before they go in with final cement. Depending on what type of material the crowns are made of, the color of the porcelain can be influenced by the color of the cement that will be used to bond them in with. Typically, there are try in pastes that can be used before to check if the color can be corrected without having to send the restorations back to the lab. If that is not enough, the lab can correct the color of the porcelain without having to remake them, but again depending on what type of material they are made out of. Best of luck to you.
It sounds like years of wear on your teeth has affected your confidence in your ability to smile. I would advise you to seek a dentist who is trained in full mouth rehabilitation. From your description, the skill set needed to address your concerns is more involved than those who do "drill and fill" dentistry. Patients of ours who have undergone treatment in rehabilitating their whole mouth not only look and feel better, they often comment of how they wish they had done this work sooner because of the new found confidence and ability to function that comes along with this kind of work. Wishing you the best in your journey to find someone who can restore your smile to one you will love.
