Conditions like this are typically caused from one of 2 factors: prescription medications, or gum disease. Some medications do cause gum growth, which must be removed surgically. How long has it been since you’ve had your teeth cleaned? If subgingival tartar is present, it is causing chronic infection (inflammation) to occur, and will also cause bone loss, so it will need to be cleaned as soon as possible. Thankfully, cleanings are very affordable. There are also new advancements in laser tissue recontouring that allow tissue to be reshaped in just a few minutes, with little or no discomfort.
People with wider smiles often need to have veneers extend back farther than people who have narrower smiles. As long as an experienced cosmetic dentist places the veneers, and they are not placed in an area where they can be compromised by normal tooth functioning, then you will be just fine.
Lumineers will typically take only 2 appointments, and can be worked in around your travel schedule. The first one will be your consultation and impression, and then the 2nd one will be for the Lumineers to be bonded to your teeth. Lumineers are much quicker as far as procedure length, but the turn around time will not be as fast as 2 days. However, squeezing in an appointment when you’re in town is all that you’ll need. Unfortunately, all veneers are considered to be cosmetic, and literally no insurance companies will cover cosmetic procedures. There are 3rd party 0% interest financing plans available through many dentists.
Ideally, you should not ever have to recement an appliance such as a crown or bridge. If it happens several years down the road, that’s an indicator that it might need to be replaced. Constant recementing typically means that the restoration needs to be replaced, the cement was wrong, or something else is going on. You may need to explore some other options.
Your porcelain veneers are made to withstand the same oral care products that other porcelain restorations like crowns and bridges do. The only thing you may want to avoid is toothpastes that contain baking soda, as this abrasiveness could cause microscopic scratches over time.
