You probably know us dentists' answers will be not to smoke at all! That being said, smoking shouldn't affect the teeth, but may discolor the temporary material faster than it would a natural tooth or a permanent restoration. Smoking weed also may significantly lower your pain tolerance threshold and affect how numb you're able to get when you're in the chair, so lay off as long as you can prior!
The sensitivity can be due to a whole host of things! Try getting a second opinion from another dentist who can see you in person!
Your dentist was right - bonding can work, but it may not last if the added bonding hits the tooth on the bottom too hard when you function or if/when you grind your teeth at night. Check if when you bite edge-to-edge with your front teeth that there's extra space to put bonding material there along the edge of the tooth. That being said, the tooth may have something else going on, being that you mentioned there was trauma involved. Trauma to teeth yields changes in the teeth that sometimes take quite some time to manifest.
A 3/4 crown is simply putting porcelain not only on the front ('facial' or 'buccal' surface) of a tooth (like a veneer), but also putting porcelain on the biting surface. Dental bonding on the facial surfaces of the front teeth are also known as composite veneers. These can be made thick or thin, and use opaque or translucent materials, crucial in determining the show-through of the natural teeth behind them. Porcelain veneers (and 3/4 crowns in the same exact way) can also be made thick or thin, and you can use opaque or translucent cements underneath them to block out the natural teeth or to let them show through. Both porcelain veneers and 3/4 crowns can be made very thing or a bit thicker. Hope that answers your question! *All advice/any statement made here should not be taken as definitive dental advice. The ideal way to obtain definitive information is with proper diagnostic procedures during an in-person consultation.
Goodness gracious, do not veneer teeth all the way in the back no one ever sees! Very few individuals smile wide enough to even show their first molars in their smile. Given how you smile, the most you should ever get is probably 10 teeth veneered up top (might want to get the 10 bottom too if you do that so they look the same). That being said, if you like the look of your other natural teeth, the lateral incisors can be veneered alone and give you a great result.
