There are various products available which we can use to clean between our teeth but the most commonly used ones are dental floss/tape, TePe brushes and floss picks. When we remove the food from between our teeth before brushing with fluoride-containing toothpaste, we reduce our risk of caries significantly.
During your routine dental check-up, your dentist or nurse may take radiographs. We take these regularly to check for caries, to check bone levels and to ascertain the integrity of existing restorations. (See https://keithdental.co.uk/radiographs-as-a-diagnostic-tool/ for more information).
It is also important to have something called a fissure sealant done on all newly erupted posterior teeth. The pre-molar and molar teeth have what we call pits and fissures on the chewing surfaces, and sometimes these fissures do not close completely during formation. Therefore your dentist or hygienist may do a small sealant restoration on these teeth when they come into the mouth to prevent food and bacteria getting into the fissures and causing caries.
Prevention is the best way to keep our teeth and gums healthy and in doing so we keep ourselves healthy too!
