Dental Floss
Dental floss is a waxed or unwaxed thread made of either nylon filaments or plastic ribbon, and which is primarily used to remove any remaining food or dental plaque that may remain on the surface of the tooth or in the gaps between the teeth. It is used by gently inserting between the teeth and is passed/scraped between the teeth close to the gums.
The dental floss can be waxed or unwaxed, and flavored or non-flavored.

Toothache - Causes, Prevention and Treatment
Toothache is a condition where the tooth or its surrounding gums cause extreme pain due to one of the several reasons. It can be lesion or an inflammation to the pulp that can lead to pain in that region and it effects the whole body of the tooth.

What is the treatment for toothache?
- Temperature Sensitivity - This is one of the most common causes, in which any contact to very hot or very cold temperature suddenly causes sensitivity to the tooth and causes pain. This is more prominent when the tooth surface has been worn out earlier and the dentin part of the tooth is exposed directly to the extreme temperatures and the dentinal tubules show the maximum sensitivity.
Root Canal
Root canal is a dental procedure which helps in removing the entire internal parts, mainly pulp chamber of the tooth. It also 
involves the filling of the prepared empty cavity with a suitable bio-compatible material. This procedure is done and advised only when the tooth can not compensate restoring material in a small cavity on the surface. The procedure involves the removal of the nervous elements of the tooth which have been infected or decayed already due to microbial action or any physical pressures.
The procedure that involves the root canal is also called as root canal therapy or root canal treatment. This is the only procedure that can help when the entire pulp and its contents are decayed. This procedure of root canal treatment can be done by a general dentist, but the one who specializes in this field is an Endodontist.
What is a spillway space or embrasure?
Definition - When two tooth in the same arch are in contact, their curvature adjacent to contact areas form spillway spaces also called embrasures. The spaces that widen out from the area ne contact labially or buccally and lingually are called labial or buccal and lingual inter proximal embrasures.
The embrasures are continuous with the inter proximal spaces between the tooth.
Above the contact areas incisally and occlusally, the spaces which are bounded by the marginal ridges as they join the cusps and incisal ridge are called as the incisal or occlusal embrasures.
Incisal or occlusal embrasures, and the labial or buccal and lingual embrasures are continuous.
What is a cusp?
A cusp is an elevation or mound on the crown portion of the tooth making up a divisional part of the occlusal surface.
In humans, the cusp are formed in posterior teeth i.e. The molars and premolars. The cuspal arrangement in the maxilla and mandible should compensate with each other so that correct occlusion occurs or this can lead to attrition.
The first premolar has a large buccal cusp which is well formed with non functioning lingual cusp.
The second premolar has three well formed cusp i.e. One large buccal cusp and two small lingual cusps.
The maxillary first molar has four well developed functioning cusp and one supplemental cusp. The four large cusps are mesiobuccal, distobuccal, mesiolingual, distolingual. The supplemental cusp is called as tubercle of carabelli.
