The term 'SOME BRIDGES CONNECT THEM' can be solved by the five-letter word 'TEETH'. TEETH are a type of hard, calcified structures found in the jaws of many vertebrates. They are used for biting and chewing food, as well as for defense and other specialized functions. TEETH are connected to each other by bridges, which are made of either metal or porcelain. These bridges help to keep the TEETH in place and provide support for the jawbone.
