I recently had an accident & I’ve been told by my dentist that my upper front tooth has split and needs to be removed. Can I wait until it pains me before it is removed or should it be dealt with sooner?

When a tooth is so badly damaged that your dentist recommends its removal then as a rule it should be removed ASAP. This is especially true with a split front tooth because bacteria can get into the tooth and surrounding bone and cause extensive damage in a short time. If the bone is extensively damaged it may take several advanced procedures to reconstruct it and in extreme cases it may be unfixable.
