A 1999 Honda Civic has an interference engine, so yes it will destroy the engine if the timing belt brakes... ok maybe not destroy but the damages will cost more then a used engine and it costs about $300 to have the timing belt and water pump changed on a good engine, if your timing belt brakes on a non interference engine then your best case is that you have to have the car towed to have it repaired so right there is $100 to $200 on top of the repair and while they tend to last 120,000 miles or so, it is a good idea to change the timing belt at nice round numbers like 200,000 miles.

If the timing belt does brake it will bend valves, damage valve guides and can damage pistons, so at the very least you would need a rebuilt head.
