Chewing gum is available in a wide variety of flavors, including  mint, wintergreen, cinnamon and various types of fruits. Mintier  flavors are often chewed for fresher breath. There is no standard type  of gum, as it can be formed in many different shapes and sizes. Some  examples include:

 
• Ball gum - shaped like a ball and coated. These are most often sold in gum ball machines.  In the United Kingdom, these are often referred to as 'Screwballs', as  they are found at the bottom of a 'Screwball' ice cream treat. In the  US, they are known as "gum balls".
 
• Bubble gum - formulated with film-forming characteristics for blowing bubbles.
 
• Sugarfree gum - made with artificial sweeteners.
 
• Candy & Gum combinations - predominantly bubble gum found in the center of some types of lollipop, such as Charms Blow Pops.
 
• Center-filled gum - Pellet or ball gum formed around a soft or liquid centre.
 
• Slab gum Cut & Wrap gum - refers to the name of the machine that wraps this type of gum, usually in the form of a chunk, cube or cylindrical shape.
 
• Dragée gum or "pellet gum" - a pillow-shaped coated pellet, often packed in blister packs.
 
• Functional gum - a chewing gum with a practical function. Zoft Gum,  for example, specializes in herbal chewing gum products using gum as  the delivery system for vitamins and minerals among other substances.
 
• Medicated gum - a chewing gum acting as a delivery system to  introduce medicinal substances into the saliva and thus into the  bloodstream faster than pills.
 
• Powdered gum - free-flowing powder form or powders compressed into unique shapes.
 
• Stick gum - a rectangular, thin, flat, slab of gum.
 
• Ribbon gum - very similar to stick gum in shape, but much longer, coiled up in a cylindrical container often shaped like a hockey puck. The chewer tears off a piece of the desired size.
 
• Tube gum or Spaghetti gum - very soft bubble gum which can be squeezed from a tube or can be found in a pouch.
