When you leave the surgery you will still be numb for a few hours until the local anaesthetic wears off.
Avoid hot foods and drinks while you are numb. When you are drinking liquids always drink from a glass and avoiding drinking with a straw. The sucking motion when a straw is used can dislodge the blood clot and cause the bleeding to start again.
For the first day you should stick to a diet of soft foods that do not require much chewing. Each day after you can advance your diet to what is tolerable, remembering to keep up a nutritious diet.
During your first few days after surgery your quantity of food will be limited, so it is very important to keep up a high fluid intake to prevent dehydration. Avoid skipping meals, as you will feel better and have more strength and heal faster if you continue to eat regularly.
