Every now and then when im riding my bike i here this dinging noise on my front wheel disk break. I took it back to the bike shop and the person said that the rotor is perfectly lined up and everything is fine. But every know and then i hear it (Its not always). Do i have to worry about this?????

What bike/forks/brakes?
Check everything is tight - qr/axle, caliper mounting bolts - and if so carry on and don't worry.

Some brake calipers use an 3mm allen bolt to hold the pad and some use a metal split pin these are on the cheaper brakes.
its not disc brake rub when you turning into a corner or anything? I've had this on wheels that aren't as stiff.
Any unusual noise is cause for concern, it means that something has changed.
Ignoring it is just storing up trouble that is sure to cost more to deal with it later.
Silent is best.
Typical causes are :-
Calliper is not aligned properly
Brake pads not in properly
Something has got in behind the pads reducing the gap between the pads
The calliper needs resetting
Rotor is bent or damaged
There is too much fluid in the brake making the pad gap too small
Wheel is loose and QR / Thru axel needs to be tighter
Loose bolts on calliper
The cheap disc brakes tend to do this how ever you set them up but anything Deore standard or better should be fine.
If it is more of a grinding or squeaking noise then look at wheel bearing or end caps to make sure everything is greased enough.
Good Luck
Usually a 5mm allen key.
What bike/forks/brakes do you have?

That may be useful. Since no one here has seen the bike nor head the noise, together with the lbs not being able to identify the cause, then all the above is speculation and guesswork.
Of course it's speculation and guesswork from us all. I'm sure the OP is happy with that as he is looking for something he hasn't thought of.
Am bit fed up of the samo posts my bike is creaking /discs are squeaking by people who post once never to return.
Surely a search would provide answers, maybe there should be a faq or sticky post.
My bike is a Saracen Mantra Trail 2018
Don't worry though, I've looked it up - Shimano M396 brakes.
The pads are held in place with a split pin and are not a particularly tight fit. It is probably worth taking the pads out and making sure the retaining spring is in place and the not bent as this could be catching the disc and causing the pinging sound.
If that is all ok then try realigning the brake calliper.
