Least Invasive option for mild tooth erosion and craze lines? (Photos)

Hi there
My name is Clifford; I qualified as a dentist in 1983. So next year will mark 40 years that I have assisted patients like you with these questions.
I want to make my answer as straightforward as possible, so I will try to answer each statement/question separately and then possibly conclude with some ideas on what to do going forward.
I had bulimia for years as a teen, as well as a grinding habit.
ANSWER 1: on looking at the photos, it's not possible to see the palatal surfaces of your upper teeth. These areas are most often affected by the acid and regurgitation contents.I don't see any signs of grinding causing severe wear to your eye teeth and premolars. I also don't see any thinning of your upper teeth. So I have great news for you! I think your teeth look fantastic.
I'm looking for a way to enhance my smile, so I'm not so insecure about it anymore.
ANSWER 2: I can see that you feel insecure about your smile and your history of grinding and bulimia. Still, as far as I can see from your photos, the main drawback of a perfect smile is your dental arches could benefit from widening and rounding out the triangular arch form into a nice big white smile.Either braces or clear aligners would work.My Choice for you would be Genuine Invisalign with an experience level of gold or platinum at least. They should also be using the iTero scanner. Make sure it is Invisalign, there are a lot of copies out there, claiming all kinds of stuff.
I have some craze lines on my front two teeth and lower front teeth (as well as mild erosion on the bottom front two).
ANSWER 3: Craze lines are normal and not a sign of grinding or bulimia if you whiten your teeth with custom gel trays and 6% HP dispensed by a professional dentist who has examined your teeth.
I am afraid of veneers since I want to be considerate of my natural tooth health. ANSWER 4:That is an excellent reason, and you are 100% correct. However, veneers would do nothing for your teeth other than damage them forever. Especially if the dentist told you he would also straighten your teeth with these magic veneers.
Would cosmetic bonding be possible?
ANSWER 5:If you need bonding, then the latest technique for bonding uses a 3D scan, special software called DSD digital smile design, and 3D printed models.The dentist uses a very clear silicon mould over the model and can then place this over your tooth. Next, he squirts a liquid ceramic over your tooth, taking the shape of the mould. Finally, a special light is used to harden this porcelain-like material.The mould is lifted, and the perfect new tooth is effortlessly polished.
Would zoom whitening hide the cracks?
ANSWER 6:
Zoom whitening uses a very bright and warm light. So I do not recommend it in your case. Instead, I recommend take-home trays with an alternative product that your dentist can recommend. In your case, I would use one of the four favourites we use at OptiSmile in Cape Town. The one I would use for you is the only one that has the patented "NOVON" technology. I am not in love with the brand name, but it's a good product. It's called "White Dental Beauty". While you are whitening, blotches and cracks may appear more noticeable. In a few days after you are done, and the saliva rehydrates the tooth; most people look amazing.
