Pressure build up in front tooth

[RONFAIRBROTHER]

I'm having difficulty getting this through to my dentist so maybe someone can help here please.
When cold air or fluids contact my left front tooth, I feel a build up of pressure which remains painful, until I continue covering it in cold and until it finally gives with a pressure relieving pop. At that point the pain is removed for a while until the same happens again. This comes and goes but has been more persistent the last week. Is anyone else suffering the same and found the cause or are there any dental experts aware of this symptom please
Thanks
