Final answer:
Poor oral hygiene can lead to the buildup of biofilm on teeth, significantly increasing the risk for dental problems and serious health conditions such as atherosclerosis and endocarditis. Biofilms are resistant to treatment and can affect a range of environments, not just the oral cavity.
Step-by-step explanation:
Poor oral hygiene techniques can lead to the accumulation of biofilm on the surfaces of teeth. If not properly removed through effective brushing and flossing, this biofilm can contribute to the formation of dental plaque, which houses harmful bacteria such as Streptococcus mutans. This bacterium is a primary contributor to dental caries (tooth decay) and can harden into tartar with time. Moreover, it's not just about cavities; biofilms can have broader impacts on health, including increasing the risk for cardiovascular diseases like atherosclerosis, and serious conditions such as endocarditis. Streptococcus mutans can enter the bloodstream during dental procedures or even routine tooth brushing, leading to inflammation and potentially severe health consequences.
Additionally, biofilms are notorious for their presence in various environments, including medical settings where they can cause infections associated with medical devices like catheters and prosthetic joints. Biofilms can be challenging to treat as they exhibit strong resistance to antibiotics and require advanced medical interventions for eradication.
