Sometimes, it is hard enough getting ahead in the city of London: it’s a demanding place and can place a lot of pressure on you, but it’s not totally impossible to make your way and if you give it your best shot, present yourself professionally and keep yourself healthy, there is no reason why you shouldn’t do well at work and have a good pool of friends socially. But, and it’s a big but, if you suffer from bad breath, you are on to a loser on all fronts from the start, though getting to the bottom of the problem can be quite complex. Many factors can cause this condition, from bad lifestyle, bad oral hygiene and bad diet to more sinister things deep inside you, which adds up to making it difficult to overcome. Once you realize you have bad breath, the first stop should be your dentist and your hygienist to check on the condition of your teeth and gums: gum disease and tooth decay can help promote foul odours in your mouth. If this works out okay, then you need to sit down and discuss your overall diet and your lifestyle and see how you can improve them; maybe cutting out smoking and drinking and eating more healthy in order to build up your immune system. Oral hygiene needs to be changed too, so you will need to look at ways of improving it. However, bad breath can be caused by gastric problems inside you, and if bad breath persists once you have taken the obvious precautions, then you may need to see a doctor.
