Bad breath, or <strong>halitosis<\/strong>, is among the first signs of an <strong>imbalance in oral pH<\/strong>. It is a condition that can be a source of embarrassment, but fortunately it is often resolvable. In the case of oral acidity, this unpleasant discomfort is <strong>caused by bacterial proliferation.<\/strong> These microorganisms feed on sugars and carbohydrates, and their waste products are rich in acidic substances, which further acidify the environment. <strong>Reduced saliva production implies a diminished effectiveness in its buffering role <\/strong>\u2014 and therefore in controlling the bacterial population \u2014 which, growing unchecked, can expose us to the <strong>risk of cavities.<\/strong>     <\/p>\n<p>This is another danger to contend with when oral pH drops too low. Our teeth are covered by a layer composed of an extremely resistant material: enamel. Hard and robust, enamel is nonetheless sensitive to acids, which can damage its surface and compromise its protective function. <strong>A mouth with a pH below 5.5 will be sufficiently acidic to cause enamel erosion<\/strong>, thereby exposing the tooth to attack by harmful microorganisms. When erosion progresses to the point of thinning or perforating the enamel, the development of cavities becomes a real risk.   <\/p>\n<p>[\/et_pb_text][et_pb_heading title=&#8221;How to Tell If Your Oral pH Is Acidic&#8221; _builder_version=&#8221;4.27.6&#8243; _module_preset=&#8221;default&#8221; title_level=&#8221;h2&#8243; title_font=&#8221;museojhslab-700-woff||||||||&#8221; title_text_color=&#8221;#004687&#8243; title_font_size=&#8221;25px&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_heading][et_pb_text _builder_version=&#8221;4.27.6&#8243; text_font=&#8221;museojhsans-300-woff||||||||&#8221; text_text_color=&#8221;#444444&#8243; text_font_size=&#8221;16px&#8221; link_text_color=&#8221;#f2b858&#8243; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p>Some warning signs are easy to recognise: <strong>acidic saliva tends to be associated with a bitter sensation in the mouth.<\/strong> If the situation persists long enough, we may begin to notice an <strong>increase in dental sensitivity<\/strong> to both heat and cold. <\/p>\n<p>The most common symptom of an acidified oral cavity, as we have seen, is halitosis caused by bacterial proliferation.
