A quick pre-vacation checkup by your dentist may be a good idea. This is especially important if your travels take you to remote areas of the world. Always avoid sticky or hard exotic foods that you are not used to eating. You can construct an inexpensive dental kit to take on your trip. Dental cement compounds are available to replace a filling temporarily.
Orthodontic wax protects sharp edges, especially on braces.
A pair of tweezers, a small mirror, sterile cotton, and a denture repair kit with adhesive may also come in handy. Although you can create a temporary filling, do not take any chances with a broken or abscessed tooth. See a dentist as soon as possible. Be sure to pack your dental insurance card with policy number and your local dentist's phone number. Cruises almost always have an doctor or dentist on board.
