You can do veneer or crown to close the gap. But you need to know why you have a gap in the first place. You could have a gap because of:
1. Gum problem. A gum problem causes loss of supporting bone, making the tooth mobile and creating the gap. Therefore, closing the gap is only a short-term solution as the tooth will continue to migrate and create a gap yet again if the gum problem is not addressed.
2. If the bite is too heavy, the pressure causes the tooth to move and creates a gap. In addition to closing the gap, the bite needs to be addressed.
3. The size of the tooth is small, if the tooth in question does not have a gum problem or a bite problem, then veneer or crown will be sufficient.

There are two reasons for the receding gum line. You have recession because of gum or periodontal disease and the other because of anatomical deficiency. For anatomical deficiency, you can do gum graft, you can expect 100% of the recession to be covered. In periodontal disease, the level of the root coverage result varies by the amount of bone that is in between the teeth. Types of root coverage procedures, connective tissue graft (your own tissue from the palate), allograft (such as Alloderm, used in the hospital for burn patients), and pinhole gum graft.

How long do teeth hurt after scaling?

2. What types of food are in your diet?

4. Hand scaling vs. cavitron vs. piezo vs. airflow.
The root surface is more sensitive than enamel; the more exposed the root surface, the more sensitivity and pain you will experience. Avoid acidic food groups, such as wine, limes, lemons, and citrus. Any food with a pH of less than 6.5 can cause sensitivity and pain, however, the lower the pH, the worse it will be. Some hygienists may be more heavy handed than others. Air flow therapy by Hu-Friedy can soften the hard calculus, making it easier to remove, therefore less trauma to the root surface and less pain.
