What happens next to the gap
This question usually gets asked late. Better to know now.
After an extraction the bone loses its load and starts to resorb — about 25% of its volume in the first year. The neighbouring teeth tilt into the gap, the opposing tooth drifts out of place and the bite is disturbed.
That is why the gap is best restored within 3-6 months, while there is still enough bone. Later it is still possible, but bone augmentation is often needed by then, which makes treatment longer and more expensive.
The exception is a wisdom tooth — it does not need replacing.
The options are an implant (which preserves the bone) or a bridge. The full list is in the price list.
