Black lines at the gum line are common due to darkening of the tooth after having an root canal treatment. However, with the proper restoration, i.e. a Zirconium crown, there is a high likelihood that we can mask the black line. You definitely want to avoid a PFM if black lines are of concern to you. Good luck!
The best way to treat your situation is to schedule an initial consultation with an Orthodontist to discuss what options you have to open up the space for the lateral incisor without extracting a premolar, as well as to shift the midline back in to the correct position. After the orthodontic treatment is complete, you will need to have an implant placed in the position of the missing lateral incisor and allow 4-6 months for this to heal prior to loading this with a crown. At the time your restorative dentist is having the implant crown made, he/she can also have a matching veneer made for your peg lateral. I also recommend having a Nightguard made to protect the implant after it is placed. Good Luck!
This is a very unique situation. It is very rare for an implant to break. (In the past, small diameter implants had a higher failure rate.) However, to have 2 implants break makes me wonder: could you be grinding or have a particular biting or clenching bite that your previous dentist did not evaluate properly? At this point, unfortunately, your best option is to evaluate your bite and determine which is the best implant and implant angle for your mouth. I also highly encourage you to have a mouthguard made for you after the implants are placed. Good Luck!
When Lumineers or any restoration are placed properly most of the complications listed should not be experienced. The reason for #1: Halitosis- may be due to: poor seal on the restorations which allows bacteria to gather at the margins of the restoration and can create Halitosis (bad breath); #2- Breaks or cracks: can be due to improper bonding or an inaccurate bite. The breaks can also be due to a patient that is grinding his/her teeth and not wearing a Nightguard to protect the restorations; #3- Gum disease: Can be due to the improper placement of the restorations causing irritation of the gums. This could be because the restorations were placed too deep into the tissue. When restorations are placed above the gums, they allow for better tissue healing and a healthier more cosmetic appearance.Good luck!
Lumineers and non-prep restorations can be bonded to crowns. However, I do not recommend this method because it will add bulk to your teeth and make your teeth appear to be a lot bigger than they are. The best option is to remove the crowns and have Cosemetic Emax crowns placed. Good luck!
